Calaxon icon: a calendar page with one date ringed by an orange alarm clock

Calaxon

Calendar reminders, loud as an alarm

Keep the calendar app you already use. When a reminder you care about goes off, Calaxon rings like an alarm clock: loud, repeating and full screen, even when your phone is on silent.

Full-screen alarm for a 4:00 PM dentist appointment, with 5, 10 and 15 minute snooze buttons and a large Dismiss button. Settings screen with switches choosing which calendars ring, across two accounts. Keyword setting turned on, so only events with an exclamation mark in the title ring as alarms. Warnings that alarm volume is off and Do Not Disturb is blocking alarms, each with a button to fix it.

Rings like an alarm clock

Alarm volume, repeating until you answer, and full screen over the lock screen. Snooze for 5, 10 or 15 minutes with one tap.

Keep your calendar app

Calaxon rings at the moment your calendar's own reminder goes off. Nothing to copy over and nothing to sync. Works with Google Calendar.

You choose what rings

Pick the calendars that ring, or only events you mark with a keyword like “Dentist !”. Everything else stays a normal notification.

Warns you if it can't ring

Alarm volume at zero, Do Not Disturb blocking alarms, a missing permission: Calaxon spots each one and shows you how to fix it.

Private by design

No internet access, so your calendar never leaves your phone. Calaxon only reads it and never changes it. No account, no ads, no tracking.

Free

No ads, no subscription and no in-app purchases. For Android 13 and newer.
