The 14 Best Calendar Apps for iPhone in 2025

I’ve spent countless hours testing calendar apps.

Downloading them, setting up schedules, syncing them with my other apps, and seeing which ones actually make life easier.

Some were impressive, some were frustrating, and a few completely changed how I manage my time.

If you’re tired of generic recommendations that don’t tell you why an app is great (or who it’s best for), you’re in the right place.

This isn’t just another roundup.

I’ve personally tested every app on this list, and I’ll break down exactly what makes them worth using.

Let’s get into it.

1. Fantastical – I Like it the Most

Pros:

• Beautiful, easy-to-use design
• Powerful natural language input
• Advanced scheduling and task management
• Syncs with Apple Calendar, Google, Outlook, and more

Cons:

• Free version is very limited
• Premium subscription is pricey

Price: Free, $6.99/month, or $56.99/year.

Get it from: App Store

Fantastical has been my go-to calendar app for a while, and for good reason.

It just works.

Unlike many other calendar apps, it doesn’t feel clunky or overwhelming.

Everything is neatly organized, and adding events is as simple as typing “Lunch with John at 2 PM on Friday.”

The app understands and schedules it instantly.

One of the standout features is its calendar view options.

You can switch between different layouts, see your tasks alongside events, and even get weather forecasts built right into your schedule.

If you manage multiple calendars (work, personal, family), Fantastical keeps them all in sync without making things messy.

Another big win is the event scheduling feature.

Instead of going back and forth to set up meetings, you can send your availability and let others pick a time that works.

This is super useful if you often plan meetings or calls.

That said, the free version is pretty limited.

You won’t get the best features unless you pay for the premium plan.

And yes, the subscription isn’t cheap.

But if you need a powerful, reliable calendar app that makes scheduling effortless, Fantastical is the best pick.

2. Apple Calendar – Best Free Calendar

Pros:

• Completely free with no ads or subscriptions
• Syncs seamlessly across all Apple devices
• Simple and easy to use
• Works with Siri for voice scheduling

Cons:

• Lacks advanced features like smart scheduling
• No built-in task management

Price: Free

Get it from: App Store

If you use an iPhone, you already have Apple Calendar.

And for a lot of people, that’s all they need.

It’s free, simple, and does a great job of keeping your schedule organized without any extra hassle.

Since it’s built into iOS, it syncs perfectly across your iPhone, iPad, Mac, and even Apple Watch.

One of the best things about Apple Calendar is how smoothly it integrates with everything.

You can add events through Siri (“Remind me about my meeting at 3 PM tomorrow”), get alerts on all your devices, and even sync calendars from Google, Outlook, or other services.

For a basic scheduling app, it does the job well.

You can create events, set reminders, invite others, and view your schedule in different layouts (day, week, or month).

It’s not overloaded with features, which makes it a great choice if you just want a simple, no-fuss calendar.

That said, it lacks advanced tools like AI scheduling, task management, or built-in templates for work planning.

If you need something more powerful, you’ll probably outgrow Apple Calendar quickly.

But for everyday users who want a reliable, free calendar that just works, this is the best option.

3. Google Calendar – Best Cross-Platform Calendar

Pros:

• Works on iPhone, Android, and web
• Seamlessly integrates with Gmail and other Google services
• Smart event suggestions and automatic scheduling
• Completely free with no hidden costs

Cons:

• Not as visually polished as other calendar apps
• Limited offline functionality on iPhone

Price: Free

Get it from: App Store

Google Calendar is hands down the best option if you need a calendar that works everywhere.

Whether you’re using an iPhone, Android, or a computer, your schedule stays perfectly in sync.

It’s completely free, and if you use Gmail, Google Meet, or Google Drive, everything ties together seamlessly.

One of the best things about Google Calendar is its automation.

If someone emails you about a meeting, Google can automatically add it to your calendar.

It also suggests event titles, locations, and times based on your past habits.

So you don’t have to type everything out manually.

For people who manage both work and personal schedules, Google Calendar makes it easy to create multiple calendars (one for work, one for personal, etc.), all viewable in one place.

You can also share your calendar with family or colleagues, making collaboration super simple.

The only downside?

The iPhone app isn’t as powerful as the Android version and offline access is limited.

Plus, while the design is clean, it’s not as visually polished as something like Fantastical.

But if you want a powerful, free, and cross-platform calendar app, Google Calendar is the best pick.

4. Microsoft Outlook – Best Business Calendar

Pros:

• Perfect for managing work emails and calendars in one place
• Seamless integration with Microsoft 365 and Teams
• Smart scheduling assistant for meetings
• Works across all platforms

Cons:

• Can feel overwhelming if you just need a simple calendar
• Some features require a Microsoft 365 subscription

Price: Free, $9.99/month, or $99.99/year (Microsoft 365 Family plan).

Get it from: App Store

If you’re looking for a business-focused calendar, Microsoft Outlook is one of the best options out there.

It’s more than just a calendar.

It’s an all-in-one scheduling and email management tool, which makes it perfect for professionals who need to juggle meetings, emails, and tasks in one place.

One of its biggest strengths is the smart scheduling assistant.

If you work with a team, Outlook can show when everyone is available, making it easy to find the best time for meetings without endless back-and-forth emails.

It also integrates directly with Microsoft Teams, so scheduling video calls is effortless.

Since Outlook is designed for work, it has powerful features for organizing events and tasks.

You can create different calendars for different projects, set recurring meetings, and even use color coding to keep everything visually organized.

Plus, it syncs with Google Calendar, Apple Calendar, and other services, so you’re not locked into just one ecosystem.

The only downside?

If you’re not already using Outlook for work, it might feel like too much—especially if you just need a basic personal calendar.

Some advanced features are also locked behind a Microsoft 365 subscription.

But if you want a business-grade calendar with top-tier scheduling tools, Outlook is the best pick.

5. My Study Life – Best for Students

Pros:

• Organizes classes, assignments, and exams in one place
• Works across iPhone, iPad, and web
• Sends reminders for upcoming deadlines
• Completely free to use

Cons:

• No direct calendar sync with Google or Apple Calendar
• Lacks collaboration features for group projects

Price: Free, $4.99 per month or $29.99 per year.

Get it from: App Store

For students, managing class schedules, assignments, and exam dates can be a nightmare.

That’s where My Study Life comes in.

Unlike regular calendar apps, this one is built specifically for students, helping you keep track of everything school-related without getting overwhelmed.

One of its best features is the class schedule planner.

You can enter your timetable once, and the app will remind you of upcoming classes, assignments, and exams before it’s too late.

It even factors in holidays and rotation schedules, so you don’t have to manually adjust anything.

Another highlight is the assignment tracker.

Instead of scribbling deadlines in random places, My Study Life keeps everything organized in one spot.

It sends reminders when due dates are coming up, so you never forget an important paper or test.

The biggest drawback?

It doesn’t sync with Google or Apple Calendar, which means you’ll have to manage your study schedule separately.

Also, if you’re working on group projects, there’s no built-in collaboration tool.

But for solo organization and making sure you never miss a deadline, this app is one of the best free calendar apps for students.

6. Cozi – Best for Families

Pros:

• Shared calendar for the whole family
• Color-coded schedules for easy organization
• Includes grocery lists, to-dos, and meal planning
• Works across iPhone, Android, and web

Cons:

• The free version has ads
• No deep integration with Apple or Google Calendar

Price: Free or $29.99/year.

Get it from: App Store

If you’ve got a busy family, keeping everyone’s schedules in sync can be a headache.

That’s exactly what Cozi Family Organizer is designed for.

It’s not just a calendar.

It’s a full family management tool that helps you track events, chores, grocery lists, and even meal plans all in one app.

One of its best features is the shared calendar, where each family member gets their own color-coded schedule.

Whether it’s school events, sports practice, or doctor’s appointments, everyone can see what’s going on at a glance.

You can even set reminders so no one forgets what’s coming up.

Beyond scheduling, Cozi also includes to-do lists and shopping lists, which is great for managing household tasks.

Need to grab groceries?

The whole family can add items to the list in real-time.

So no more last-minute texts asking, “Did you pick up the milk?”

The downside?

The free version has ads, which can be annoying, and it doesn’t sync deeply with Apple or Google Calendar.

But if you want an all-in-one solution for keeping your family organized, Cozi is one of the best options out there.

7. Cupla – Best for Couples

Pros:

• Designed specifically for couples
• Shared calendar for syncing schedules
• Includes relationship-focused features like date night planning
• Private and secure

Cons:

• Limited integration with other calendar apps
• Only useful if both partners use it

Price: Free, $4.99/month, or $34.99/year.

Get it from: App Store

If you and your partner constantly find yourselves saying, “Wait, when are you free?” then Cupla is the perfect calendar app for you.

It’s designed exclusively for couples, making it easier to plan date nights, track anniversaries, and stay on top of each other’s schedules without the usual back-and-forth.

The best part?

Cupla has a shared calendar that automatically syncs both of your schedules in one place.

It shows when you both have free time, making it easier to plan quality time together.

Beyond scheduling, Cupla also comes with relationship-friendly features.

You can create date night ideas, track important milestones, and even set reminders for birthdays or anniversaries (so you never forget).

It’s a subtle but effective way to keep your relationship organized and stress-free.

The only catch?

Both partners need to use the app, and it doesn’t sync as deeply with Apple or Google Calendar as some other apps.

But if you want a calendar that’s built specifically for couples, Cupla is hands down the best choice.

8. Structured – Best for ADHD

Pros:

• Combines a calendar, to-do list, and planner in one
• Simple, visual timeline for organizing the day
• Helps with time blocking and focus
• Clean, distraction-free layout

Cons:

• No direct integration with Google Calendar
• Lacks collaboration features for shared planning

Price: Free, $4.99/month, $14.99/year, or $49.99 lifetime.

Get it from: App Store

For people with ADHD, a traditional calendar often isn’t enough.

You need something that helps you visualize your day in a way that makes sense.

That’s where Structured comes in.

It’s a time-blocking planner that lays out your tasks in a clean, easy-to-follow timeline, helping you stay on track without feeling overwhelmed.

The app’s biggest strength is its visual design.

Instead of just listing events, this ADHD calendar app shows your day in a clear, color-coded timeline.

You can quickly see what’s coming up, how much time each task takes, and when you have gaps for breaks or other activities.

This makes it perfect for people who struggle with time blindness and need a more structured (no pun intended) approach to planning.

Another great feature is its simplicity.

There’s no clutter, no unnecessary extras.

Just a straightforward way to plan your day.

You can add tasks with just a few taps, set reminders, and break big tasks into smaller steps so they feel more manageable.

The only downside?

It doesn’t integrate directly with Google Calendar, and there’s no way to share plans with others.

But if you need a visual, ADHD-friendly planner that helps you manage your day without feeling chaotic, Structured is an amazing pick.

If ADHD resonates with you, here are some helpful guides specifically crafted for it:

• Best productivity apps for ADHD
• Best routine apps for ADHD
• Best reminder apps for ADHD
• Best budget apps for ADHD
• Best ADHD apps for women

9. Reclaim.ai – Best AI Calendar

Pros:

• Automatically schedules tasks, meetings, and habits
• Uses AI to optimize your calendar based on priorities
• Integrates with Google Calendar and Outlook
• Helps with time blocking and work-life balance

Cons:

• No direct Apple Calendar integration
• More useful for professionals than casual users

Price: Free, $8/month for small teams, or $12/month for large teams.

Get it from: Official Site

If you’re tired of manually managing your calendar, Reclaim.ai can do it for you.

It’s an AI-powered scheduling assistant that automatically finds the best time for your tasks, meetings, and daily habits.

The way it works is simple: You add tasks, events, and even recurring habits (like workouts or focus time), and Reclaim.ai automatically adjusts your schedule based on what’s most important. It also moves things around when conflicts arise, making sure your most critical tasks always get done.

One of its standout features is Smart Time Blocking.

Instead of just dumping everything into your calendar, the app intelligently spreads out your workload, ensuring you don’t overbook yourself.

It also reserves time for breaks and deep work, so you don’t burn out from back-to-back meetings.

The biggest downside?

It doesn’t sync directly with Apple Calendar, so if you’re deep in the Apple ecosystem, you’ll need to use Google Calendar or Outlook instead.

Also, while it’s great for professionals, casual users might find it overkill.

But if you’re looking for an AI-powered calendar that does the thinking for you, Reclaim.ai is one of the smartest options available.

10. Clue – Best Ovulation Calendar

Pros:

• Tracks menstrual cycles, ovulation, and fertility windows
• Scientifically backed predictions
• Clean, easy-to-use interface
• Works without unnecessary pink and floral designs

Cons:

• No Apple Health integration for cycle tracking
• Some advanced features require a subscription

Price: Free, $9.99 per month or $39.99 per year.

Get it from: App Store

If you’re looking for a smart, science-backed ovulation tracker, Clue is one of the best apps out there.

It’s more than just a period tracker.

It helps you understand your cycle, predict ovulation, and even track symptoms without all the fluff that many other period apps come with.

Clue uses data-driven algorithms to provide accurate fertility window predictions, which can be helpful if you’re trying to conceive.

Or just want to track your cycle more closely.

You can log everything from mood changes to cramps and sleep patterns, and over time, the app gives you insights into how your cycle affects your body.

One thing that sets Clue apart is its simple, gender-neutral design.

There are no unnecessary pinks, flowers, or baby-related themes.

It’s just a clean, modern tracker built for real data.

Plus, its insights are backed by science, making it one of the more reliable options compared to apps that rely on generic predictions.

The downsides?

It doesn’t sync with Apple Health for cycle tracking, which would have been a nice feature.

Also, while the free version works well, some advanced tracking features require a paid subscription.

But if you want an ovulation calendar that actually makes sense, Clue is a top pick.

11. FitOn – Best Fitness Calendar

Pros:

• Built-in workout planner and scheduler
• Huge library of free workout videos
• Syncs with Apple Health for activity tracking
• Personalized fitness plans based on goals

Cons:

• Limited customization for non-workout activities
• Some premium content requires a subscription

Price: Free or $24.99 for 6 months.

Get it from: App Store

If you’ve ever struggled to stick to a workout routine, FitOn makes it easier by combining a fitness calendar with an on-demand workout platform.

Instead of just listing gym sessions on a calendar, it actually provides guided workouts and a structured fitness plan to help you stay consistent.

One of the best things about FitOn is its built-in workout scheduler.

You can plan your weekly workouts, set reminders, and even get personalized recommendations based on your fitness goals.

Plus, it syncs with Apple Health, so your workouts are automatically logged, making it easy to track progress.

The app offers tons of free workout videos, including yoga, HIIT, strength training, and even guided meditation.

Unlike many fitness calendar apps, most of FitOn’s features are free, with an optional premium plan for extra perks like meal plans and offline videos.

The only downsides?

FitOn is focused solely on fitness, so it’s not a general-use calendar for other types of events.

Also, while most workouts are free, some premium content requires a subscription.

But if you’re looking for a fitness-focused calendar that actually keeps you on track, FitOn is one of the best choices.

12. OurFamilyWizard – Best Co-Parenting Calendar

Pros:

• Designed specifically for co-parents
• Shared calendar with custody schedules and events
• Built-in messaging and expense tracking
• Court-approved for legal documentation

Cons:

• Monthly subscription required
• Can feel overwhelming with too many features

Price: $12.50/month (billed annually at $149.99).

Get it from: App Store

Co-parenting comes with a lot of scheduling challenges, and a regular calendar app doesn’t always cut it.

OurFamilyWizard is built specifically for co-parents, helping them manage custody schedules, coordinate events, and communicate smoothly.

The app’s shared calendar lets both parents track custody schedules, visitation days, school events, and doctor’s appointments, so there’s no confusion about who is responsible for what.

It even includes a secure messaging feature, so all communication is documented.

A big plus if legal disputes arise.

One standout feature is expense tracking, which allows parents to log shared costs like school fees or medical bills.

This keeps everything transparent and organized, reducing the chances of financial disagreements.

While it’s a lifesaver for co-parents, the app does come with a monthly subscription fee, and its many features can feel a bit overwhelming at first.

But if you need a court-approved co-parenting calendar that helps keep everything clear, documented, and stress-free, OurFamilyWizard is one of the best choices out there.

13. Howbout – Best Social Calendar

Pros:

• Made for planning events with friends
• No more back-and-forth messaging to find a time
• Real-time availability sharing
• Group chat and event polls built-in

Cons:

• Not ideal for personal or work schedules
• Requires friends to also use the app for full benefits

Price: Free

Get it from: App Store

Planning a get-together shouldn’t be a headache, but somehow it always turns into endless group chats and scheduling conflicts.

That’s where Howbout comes in.

It’s a social calendar app designed to make planning hangouts, trips, and parties effortless.

Instead of messaging everyone separately, you just create an event, pick a few possible dates, and your friends can vote on what works best.

The app shows everyone’s availability in real time, so you can quickly find a time that works for the whole group.

Plus, there’s a built-in group chat, so all event details stay in one place.

Howbout is perfect for friend groups, clubs, and even casual meetups, but it’s not a replacement for a full-fledged calendar.

You probably won’t use it for work meetings or personal scheduling.

Also, for the best experience, your friends need to use it too.

Otherwise, you’re back to texting.

But if you’re tired of never being able to find a time that works for everyone, Howbout is the perfect solution for organizing social plans without the chaos.

14. YNAB (You Need A Budget) – Best Budget Calendar

• Encourages mindful spending and goal setting
• Great for long-term financial planning

It’s about planning ahead.

YNAB (You Need A Budget) is a budgeting app with a built-in calendar that helps you stay on top of bills, plan future expenses, and track your cash flow with precision.

It’s especially useful for avoiding late fees and financial surprises.

One of YNAB’s best features is its goal-setting system, which helps you plan for big expenses like vacations, home repairs, or paying off debt.

The app also syncs with your bank accounts in real time, so your budget always reflects your latest transactions.

The downside?

YNAB isn’t free.

It requires a paid subscription after a 34-day trial.
