The 5 Best Calendar Apps in 2026
The phone calendar is one of those apps you open twenty times a day without thinking, which is why small differences matter so much: how many months you see at a glance, whether you can drag an event to move it, whether your partner can see your schedule. In this guide we compare the 5 best calendar apps in 2026 depending on whether you use it for yourself, for work or for the whole household.

TopApps analysis
Google Calendar is free, fast and creates events on its own from the flight, hotel and booking emails that land in Gmail.
Google Calendar is the default calendar on Android and the de facto standard for most people: free, fast and able to show several calendars at once (personal, work, holidays, birthdays). It creates events automatically from Gmail — flights, hotels, bookings — and syncs with almost any other service.
Pros
- Free and without limits
- Creates events automatically from Gmail
- Combines several calendars in a single view
Cons
- Limited visual customisation
- No genuinely powerful task management
- Requires a Google account
Microsoft Outlook
Microsoft Corporation · Free (with purchases) · 1.000M+
Best for work
4.6
10.6M reviews
TopApps analysis
Outlook puts email and calendar in the same app, so you can check your availability while replying to whoever is proposing a meeting.
Outlook merges mail and calendar into a single app, and that's its biggest advantage: you can check your availability while replying to an email. Its Focused Inbox separates what matters from the noise automatically, and it supports Gmail, Yahoo and iCloud accounts alongside Microsoft ones.
Pros
- Mail and calendar in one app
- Focused Inbox that filters out the noise
- Supports Gmail, Yahoo, iCloud and Exchange
Cons
- Fairly heavy on battery in the background
- The interface changes often
- Some features require Microsoft 365
TimeTree: Calendario Compartido
TimeTree, Inc. · Free (with purchases) · 10M+
Best for families
4.7
234K reviews
TopApps analysis
TimeTree is built for shared calendars and adds a chat inside each event, which is where household logistics conversations end up.
TimeTree is built specifically for shared calendars: couples, families or small teams who need everyone's schedule in one place. Each event has its own chat, so the back-and-forth about who picks up the kids sits next to the event instead of getting lost in WhatsApp.
Pros
- Designed for sharing a schedule with family or partner
- Chat inside each event
- Several independent shared calendars
Cons
- Shows ads in the free version
- Weaker as a personal calendar
- Google Calendar sync is limited
Business Calendar 2
Appgenix Software · Free (with purchases) · 10M+
Most configurable
4.6
273K reviews
TopApps analysis
Business Calendar 2 shows several months at once, lets you drag events to move them and has the most customisable widgets on Android.
Business Calendar 2 is the answer for anyone who has outgrown Google Calendar: several months on screen at once, drag-and-drop events, colour coding per calendar and widgets you can tune down to the detail. It builds on the calendars already synced on your phone, so there is nothing to migrate.
Pros
- Highly configurable multi-month and agenda views
- Drag and drop to move events
- Among the most customisable widgets on Android
Cons
- Android only
- Dense interface with a lot of options
- Pro features are paid

Any.do: Lista de Tareas
Any.do To-do list & Calendar · Free (with purchases) · 10M+
Best if you mix tasks and schedule
4.3
505K reviews
TopApps analysis
Any.do puts your to-dos and your calendar events on the same screen, useful if your day is half meetings and half errands.
Any.do rolls a to-do list, a calendar and a shopping list into one carefully designed app. Its signature feature is the daily "My Day" review, which forces you to decide each morning what you'll actually get done. It works well on your own and just as well for sharing household chores with a partner or the family.
Pros
- To-do list and calendar in the same view
- Daily planner that helps you set priorities
- Shopping list shared with the whole family
Cons
- The most useful features sit behind the Premium plan
- The free plan limits recurring reminders
- Less powerful than Todoist for complex projects
Frequently asked questions
What is the best free calendar app?
Google Calendar is the best free option for most people: no limits, several calendars combined in one view, and events created automatically from Gmail. Outlook and TimeTree are also free and make sense if you need, respectively, built-in email or a calendar shared with the family.
How do I share a calendar with my partner or family?
TimeTree is the simplest for that: you create a shared calendar, invite people, and everyone sees and edits the same events, with a chat inside each one. Google Calendar also lets you share whole calendars with read-only or edit permissions, but it is designed more for sharing your own schedule than for building a joint one.
Can I keep my work and personal calendars in the same app?
Yes, and it is the sensible thing to do. Google Calendar, Outlook and Business Calendar 2 all let you add several accounts (Google, Microsoft, iCloud) and overlay them in different colours, so you see every commitment together but can tell at a glance which ones are work. You can hide any of them with a tap.
Is it worth paying for a calendar app?
Only if the free calendar falls short on something specific: multi-month views, heavily customised widgets or syncing with work tools. For normal use, Google Calendar or Outlook cover it comfortably without paying anything. Business Calendar 2 is the one that best justifies the cost, and only on Android.
