Get Calendite.

Installing it

1. Calendite is not on Google Play yet, so this is a direct APK. Android will ask you to allow installs from your browser the first time.
2. Open the downloaded file and tap Install. Play Protect may warn that it does not recognise the app; that is what it says about every app it has not seen before.
3. This is a preview build under active development. See getting started for the first-run wizard.

Installing it

1. Calendite is not signed with an Apple Developer ID yet, so Gatekeeper may say it cannot check the app for malicious software.
2. Open the disk image, drag Calendite into Applications, then right-click (Control-click) the app and choose Open. After that it opens normally from Launchpad.
3. macOS will ask once to allow Calendite's alarm helper to run in the background; alarms need it to ring on time even when the app itself is closed.
4. Then link it to your phone: on your phone, More, Share calendar, Use Calendite On A Computer, and scan the code it shows.

Installing it

1. There is no code-signing certificate yet, so SmartScreen will say Windows protected your PC.
2. Click More info, then Run anyway, and follow the installer.
3. Alarms ring as Windows' own toast notifications, so they still work with Calendite closed.
4. Then link it to your phone: on your phone, More, Share calendar, Use Calendite On A Computer, and scan the code it shows.

Linking it to your phone

1. Go to web.calendite.com on your computer.
2. On your phone: More, Share calendar, Use Calendite On A Computer, then scan the code it shows.
3. Your calendar appears in the browser and stays in step from then on. See sharing your calendar for linked devices, locking and unlinking.
