Features
Four ideas, one app. Built from scratch in Kotlin for Android.
End-to-end encrypted messages
Gift-wrapped private messages hide who you talk to, when, and what you say. Relays only ever see sealed envelopes.
- NIP-17 gift wraps
- NIP-44 v2
- Keystore-encrypted keys
Forests and shared gardens
Points from meaningful use grow procedural trees. Message points are capped each day, so the forest rewards care, not spam.
- 8 tree species
- Spring physics
- Synced without syncing
Daily eco challenges
Thirty small actions across energy, transport, food, waste, water and nature. Do one yourself or send it to a friend as an interactive card.
- 30 challenges
- Challenge a friend
- Achievements
Gentle on the planet
Background sync only runs while charging on Wi-Fi. Efficiency mode turns on the dark theme, calms animations and cuts background work.
- Carbon-aware sync
- Impact dashboard
- Efficiency mode
How it feels
Small touches that make a messenger feel alive.
- Living skyFollows the real time of day: sunrise, the sun and moon arc, stars and clouds.
- Trees with physicsProcedural trees sway, grow with spring physics and shake when you tap them.
- Particle burstsLeaves, petals and sparks fly when you send, react or unlock an achievement.
- Haptics everywhereBouncy buttons, animated tabs and gentle feedback on every touch.
- A mycelium networkSee your relays as a living network with data packets flowing to each one.
