I didn't get as much time on this as expected, but I'm pleased with it as an MVP. My goal was to see how unobtrusive and non-nostr I could make a useful thing.
Your npub is your account, tasks are NIP-44 encrypted, stored on relays you already use. No server, no signup.
What works today:
- Sign in with any NIP-07 extension
- Create private encrypted lists
- Add, edit, complete, delete tasks
- Share lists with other npubs (NIP-05 lookup supported)
- Data syncs across devices via relays
What's next:
- Due dates + priority levels
- Relay configuration
- Public projects with bounty tasks + zap payments
Try it:
Zaptask - Encrypted Tasks, Your Keys

Early stage—would appreciate testing and feedback. Events go to damus, nos.lol, and nostr.band relays.
