02 / THE DETAILS MAKE THE DIFFERENCE
01

Hard to miss. Easy to love.

Persistent full-screen reminders stay with you until you act. Snooze when life happens, then come back on your terms.

02

Less typing. More doing.

Build a reminder with the phrase composer. English and Greek interfaces make your everyday language feel right at home.

03

A companion, offline.

100 detailed pixel illustrations bring personality to your day. Reminders work offline; cloud-folder sync and backups are optional.

FROM THE REAL APPLICATION

A home for every little quest.

The QuestBell dashboard, straight from the project repository.

Release notes ↗SHA-256 ↗

The installer is unsigned. Reminders stay local unless you explicitly enable optional cloud-folder sync.

04 / GOOD TO KNOW

A few answers.

Something else on your mind?

Open an issue
Do I need an account?+

No. Reminders work offline without signing in. Update checks need an internet connection.

How does cloud sync work?+

You choose a private folder managed by your existing cloud desktop client. QuestBell itself does not sign into a cloud provider. Sync and backups are off by default.

Will Windows show a security notice?+

The installer is unsigned, so Windows may show an unknown-publisher or SmartScreen notice. Download only from the linked GitHub release.
