About this app

Prove your work, block by block. Most habit trackers give you a checkbox and a streak that breaks the moment you miss a day. Satoshi Habits keeps what you actually did. Write down what matters. Confirm it when it's done. Every 21 confirmations seal into a block — and the blocks become your own chain, on your phone, growing for as long as you keep going. Nothing resets, nothing expires. Open it in six months and see everything you got done. FIRST, THE PART PEOPLE ASK ABOUT You never buy or receive Bitcoin in this app. What you earn is Proof of Work points, and they stay points. There is no wallet, no balance to withdraw, nothing to cash out. What you do get is the real thing explained as you go: what a satoshi is, how a block gets built, what difficulty means, why 21 keeps coming up. If you ever decide you want to own some, the app points you to a trusted broker and you buy there, in your own account. If you never do, nothing here stops working. Built for someone meeting Bitcoin for the first time, and still interesting to someone who has been down the rabbit hole for years. WAKE UP TO NEW BITCOIN BLOCKS Grind gets you to sleep and out of bed. Sleep sounds and music to fall asleep to, and an alarm — iOS 26 or later — that hands your wake-up to iOS itself, so it rings even when the app is closed. It pays you Proof of Work for actually getting up. Hit snooze and you lose some. Fight the snooze. Signal is where you focus: sessions of 21, 45 or 60 minutes, with a record player you drag out of its sleeve, a six-slider ambience mixer, or a live radio every listener hears at the same second. COLLECT SATOSHI CARDS One hundred of them. Fifty unlock through progress, fifty come from a pack you open once a day. Together they're a Bitcoin education in disguise — you learn what a satoshi is by pulling the card. In Signature you design your own. A person reviews it, and then it joins the pool everyone else draws from — someone in another country opens their pack and gets your card. STUDY BITCOIN WHILE YOU WORK ON YOURSELF Mempool shows the network live: the block being built right now, what it costs to send, the last blocks mined. Timechain calculates what buying regularly — or all at once — would have done at any point since Bitcoin began. Power Law is a long-term model of the price. A model, not a forecast. Rabbit Hole is where you go deeper: books, links, hardware. Miner connects to a small mining machine on your own Wi-Fi — Bitaxe, BitForge and AxeOS devices — and turns your phone into its dashboard. None of it is homework. It's there when you're curious and out of the way when you're not. NO ACCOUNT, NO CATCH No sign-up, no password, no email. The core runs entirely offline on your iPhone, and your data lives in your own iCloud — never on our servers. The app is free. The optional subscription gives you three cards per pack instead of one, one exclusive card, and two panels in gold. 99 of the 100 cards are collectible without it. No feature is locked.
