Odd/Even Alarm Clock

An alarm clock for everyone whose week differs between odd and even weeks – and who does not want to be woken on public or school holidays. Made for Czechia and Slovakia.

ODD AND EVEN WEEKS
• Every alarm can ring every week, only in odd weeks or only in even weeks.
• The top of the main screen always shows which week it is. When two odd weeks follow each other (after a year with 53 weeks), the app says so.
• Counting by ISO calendar week number, or strict alternation across the turn of the year. One button aligns the app with your school.

PUBLIC AND SCHOOL HOLIDAYS
• The alarm stays silent on public holidays – computed on the phone, Easter included.
• Optionally also during school holidays: autumn, Christmas, half-term, spring, Easter and summer.
• Spring holidays for your district (Czechia) or region (Slovakia).
• Each alarm can have its own district – e.g. when children go to schools in different towns.
• Link your school's calendar (iCal) and the app finds its extra days off.
• Vacations and your own days off: alarms stay silent on the days you choose.
• Or the other way round: ring only during school holidays, or only on public holidays.
• When tomorrow is a working day and no alarm will ring, the app tells you why – e.g. "Autumn holidays".
• Skip a single ring.

A RELIABLE ALARM
• Full-screen ringing on a locked phone, with snooze and dismiss.
• Works after a reboot, even before the phone is unlocked. If the phone was off at ring time, it tells you.
• Optionally rings through Do Not Disturb when it would otherwise be silenced.
• A ringtone from the phone or the app's own wake-up melody, gradual volume, vibration, auto-silence.
• A notification 12 hours ahead with a Skip button – so in the evening you know it will ring in the morning.
• A widget with the next alarm and the odd/even week, and a "Skip tomorrow" quick settings tile.

LOXONE
• Have a smart home with a Loxone Miniserver Gen 2? The phone's alarm sets and switches on alarm clocks in Loxone ahead of time – e.g. lights and blinds, in several rooms at once.
• Loxone then runs the morning scene on its own, even if the phone is offline by then. The app can check that the Loxone alarm clock is really set.

BACKUP
• Save your alarms, days off and settings to a file, e.g. to move to a new phone – no Google account needed.

PRICE
One alarm is free. Unlock unlimited alarms with a one-time purchase – no subscription.

NO ACCOUNT, NO ADS
The app collects no personal data. It connects to the internet only to download school holidays from the OpenHolidays API (openholidaysapi.org, data under the ODbL licence), your school's calendar if you add one, and your Loxone Miniserver if you link it. Current data is bundled, so the alarm works offline.
