Android Mobile App Launch

Arch Calendar is now officially available on Android. This marks our first mobile release, bringing the same simple, focused experience to your pocket.

From day one, Arch Calendar has been built around capturing what's on your mind and planning when to do it. That core philosophy hasn't changed—we've simply made it accessible wherever you are. Whether you're at your desk or on the move, you can now capture tasks instantly into your Inbox, plan your day directly from your phone, and send links straight into Arch using the system Share menu with no copy-pasting required.

We didn't build a different product for mobile. We built the same one, shaped to fit in your pocket. The same Inbox. The same Calendar. Just closer to where your ideas and links appear. This is only the beginning of the mobile experience, and we'll keep refining and simplifying Arch Calendar so that organizing your day feels as natural as possible—wherever you are, on Android.

Multilingual Support

We've added support for two new languages:

• Korean (한국어) - Full interface translation for Korean-speaking users

• Japanese (日本語) - Complete localization for Japanese-speaking users

You can change your language preference in the app settings. The app will automatically detect your system language on first launch.
