Full-featured month view

iPhone iPad Mac

FirstSeed Calendar was designed to work well with today's big-screen phones. The month view, which is the most frequently-used view, offers one-handed operation for most common tasks, such as viewing, adding, editing, deleting, moving, and duplicating events.

While most calendar apps require a tap or a click to go to the next or previous month, FirstSeed Calendar offers smooth scrolling of calendars so that you can get to your events quicker. 

FirstSeed Calendar syncs with Apple's Calendar app, so you can use an iCloud calendar or other online calendars to sync your events across all devices.

Fully supports iOS 16


FirstSeed Calendar strives to support new features from the latest OSes. In the latest release, FirstSeed Calendar added support for the new lock screen widgets  in iOS 16,  Support for the weather and focus filter have also been added. 

In iOS 16, the new widgets can be placed right on the lock screen, changing the way you check and view your upcoming events and reminders. The new widgets can also be used to add new events quickly just by using your voice.

FirstSeed Calendar also supports focus filter, so if you set your iPhone to "Work" mode, for example, you can choose to only see your work-related events. FirstSeed Calendar can also display weather from your current location right on the calendar. 

Condensed week view

Ever wondered why the week view needs vertical scrolling? We did, and we redesigned the week view so that you do not need vertical scrolling. Week view in FirstSeed Calendar shows the most important times to you in a grid style, while the rest of the events are shown as a list.

We have gone one step further and applied this to the Day View as well. Now you can focus on your office hours or whatever time is important to you.

Reminder support

iPhone iPad Mac

FirstSeed Calendar supports reminders as well. This means that you can manage your reminders the same way as your events.  Reminders also sync across iOS and macOS via iCloud, so that you can always keep track of your to-dos.  

The new reminders in iOS 13 and macOS Catalina is only partially supported. For example, sub reminders show up as no-due reminders. Full support will be provided in a future update. 

Natural language input

iPhone iPad Mac

FirstSeed Calendar has a powerful natural-language processing engine that lets you almost "speak" to the app to enter a new event or reminder. So you can type "Dinner at 7 pm tonight" or "Remind me to call John at noon". Or better yet, you can use Siri’s voice dictation to create new events or reminders by merely speaking directly to your phone.

Natural language input is currently available in English, German, French, Spanish and Japanese. More languages will be supported in the future versions. 

External keyboard support
