about
- description
- Cairn is a Bitcoin-only Android app for people who care about the signal, not the noise. Pin widgets to your homescreen for live price, mempool, fees, on-chain indicators, and your own watch-only stack. Open the app for the full dashboard — Cycle Lab composite, network depth, ratio context. Watch-only by design. Paste an xpub or output descriptor — Cairn tracks the balance, UTXO state, and FIFO / LIFO / HIFO cost basis. Keys never enter the app. Cairn never signs Bitcoin or Lightning transactions; if you want to spend, the app deep-links out to your real wallet. Point at your own node. Watched addresses are looked up on public block explorers by default (mempool.space first); set your own mempool, Esplora or Electrum server and they go only there. Tor, through Orbot, covers every request. No ads, no analytics, no accounts, no KYC. Your wallets, alerts and settings stay on your phone. The one exception is opt-in email alerts, which send your email address to cairn.wtf.
