iPhone
Linked notes on a radial graph. Ideas connect visually, no folders or accounts needed. Just open and write, fully offline.
Your notes shouldn't live in folders. This app links them into a living graph you can explore — write an idea, connect it, and watch your knowledge take shape.
WHY THIS APP
- Connect notes with simple [[wiki-links]] — no folders, ever
- A radial orbit graph that maps how every idea relates
- Automatic backlinks reveal what references each note
- Tags, hubs and an orphan-note finder to catch loose ends
- Instant search across everything you've written
- Export any note to Markdown — private and on-device
HOW IT WORKS
1. Capture a thought as a quick note
2. Drop a link to connect it to related ideas
3. Open the orbit graph to explore and follow the thread
Full access unlocks unlimited notes, the complete orbit graph and every power feature. Choose a weekly or yearly plan, or pay once for lifetime access.
Build your second brain today — start connecting your ideas in orbit.
Everything stays on your device — no account, no ads, no tracking.
