It started as a Bitcoin habit tracker and became a lot more. Write down tasks, confirm them, and every 21 confirmations seal into a block — your own chain, on your phone, that never resets. Around that: a live mempool, an alarm iOS rings itself with the app closed, focus sessions with a record player and a live radio, 100 collectible cards on Bitcoin history, and a dashboard for a Bitaxe miner on your Wi-Fi. You never have to own Bitcoin to use it. Free, no account, iOS.
