Calendars

Lunar birthdays, never off by a day

Pick the Chinese lunar, Hebrew, Islamic or Persian calendar and every day in the picker shows both dates, with holidays named right on the grid. Repeats follow the calendar you chose, so the 15th of the first lunar month is always the right day.

Thoughtful details, everywhere

Small touches that make it a joy to use every day.

Early reminders

Minutes, days or weeks before — or at a set time like “the day before at 8 PM”. Add several to one countdown.

Flexible repeats

Daily, weekly, monthly, yearly or custom — like every 3 weeks. It rolls on to the next one by itself.

Lovely 3D icons

62 original clay-style icons — cakes, gifts, planes, graduation caps — so each countdown looks like itself.

Dark mode & haptics

Follow the system or choose light or dark. Subtle haptics everywhere, with one switch to turn them off.

Frequently asked questions

Lunar dates fall on a different Gregorian day each year. Will reminders be wrong?

No. With the lunar calendar selected, countdowns and repeats are calculated in that calendar, so the 8th of the twelfth month is reminded on the right day each year. The same goes for the other calendars.

What’s included for free?

Unlimited countdowns, Live Activities, widgets and timers are all free. The free plan allows up to 2 reminders per countdown; iCloud sync, custom app icons and exclusive artwork are Pro.

Is my data safe?

Precizero needs no account and collects no personal data. Everything stays on your device; with iCloud sync on, it lives in your Apple Account’s private iCloud database, visible only to you.

Which devices and languages are supported?

iPhone and iPad running iOS 18 or later. The app is available in English, Simplified Chinese, Traditional Chinese, Japanese and Korean, and you can switch language in Settings.
