Using PrimeCal on Your Phone
PrimeCal is not in the Apple App Store or Google Play Store today — you use it as a mobile-optimized web app from your phone's browser, at the same address as on a computer. If you already have a PrimeCal account, sign in with your existing credentials — all your calendars and events will be there instantly.
iOS (iPhone and iPad)
- Open Safari (or any browser) on your iPhone or iPad.
- Go to app.primecal.eu.
- Sign in with your PrimeCal username and password.
- Optional: tap Share → Add to Home Screen to get a PrimeCal icon on your home screen that opens straight into the app.
Minimum requirement: iOS 14 or later (Safari).
Android
- Open Chrome (or any browser) on your Android device.
- Go to app.primecal.eu.
- Sign in with your PrimeCal username and password.
- Optional: open the browser menu and choose Add to Home screen (or Install app, depending on your browser) for a PrimeCal icon that opens straight into the app.
Minimum requirement: Android 8.0 (Oreo) or later.
First Sign-In
When you open PrimeCal in your phone's browser for the first time:
- Tap Sign In (not Sign Up — use this if you already have an account).
- Enter your username and password.
- You're in. Your calendars, events, and settings load automatically.
If you don't have an account yet, you can register at app.primecal.eu from any browser, including your phone's.
Multiple Devices
You can be signed in on multiple devices at the same time. Your PrimeCal account is cloud-based — changes sync across all your devices automatically.
Sue and Noah both have PrimeCal on their phones. When May updates a Late Family event on her laptop, both kids see the change on their phones within moments.
Signing Out
To sign out of the mobile app:
- Open the Profile tab (bottom navigation).
- Scroll to the bottom.
- Tap Sign Out.
