Daystone - Countdown Days

Daystone keeps the days that matter one glance away: a countdown to the exam, the trip, the launch — and the days since the wedding, since you first got together. Fully offline, no account, and honest about its reminders.

All your days, at a glance
A warm gradient canvas opens the app, the most urgent day sits on top in a glass card, pinned days get their own band, and every card leads with the big number: 12 days to go, 2,327 days together.

Reminders you can verify
Daystone tells you, in plain text, whether a reminder will actually fire. With notification permission on, every card shows a solid bell and a chip that says it will remind you at 9:00 that morning; if the permission is off — or the system took it back — the bell turns hollow and the card plainly says the reminder is not active. No silent failures, ever.

A day in three taps
Pick an icon, choose a date, save. Make it repeat every year, pin it to keep it close, and when the day arrives the card lights up: it's today!

Your data, take it with you
Export everything to a single JSON file and restore it on any device, any time. Your days live on your device — no servers, no account, no ads.

Made for everyone
47 languages, a true dark mode with its own dusk palette, four brand colors, and type sizes up to the largest accessibility setting without ever breaking the layout.
