TapData: Sleep & Event Log

Private by design Your data lives on your device. TapData has no account and shows no ads, and we can't see your data. One tap to log Recording an event is a single tap — no menus to dig through, no forms to fill. Built for logging in seconds, even half-asleep.

Share on your terms — encrypted When you want to share — with a doctor, a family member, anyone — you choose exactly what to include. Shared data is end-to-end encrypted so we can't read it.
