COUNTDOWNS & ANNIVERSARIES
The days that matter, at a glance.
Daystone keeps every countdown and anniversary on one calm page — with reminders that prove they'll fire. Fully offline, no account, and your data never leaves your device.

Every day, exactly where you expect it
From the first countdown to the biggest type size, everything stays on your device.





Everything you need to remember a day
All your days, at a glance
A warm gradient opens the app, the most urgent day sits on top in a glass card, pinned days get their own band — every card leads with the big number.
A day in three taps
Pick an icon, choose a date, save. Repeat yearly or pin it to keep it close — and on the day itself, the card lights up.
Reminders you can verify
Daystone says in plain text whether a reminder will fire — and shows it on every card while the permission is missing. No silent failures, ever.
Your data, take it with you
Export everything to a single file and restore it on any device. No servers, no account, no ads — ever.
