Whether you're following a DCA (dollar-cost averaging) plan or logging occasional BTC buys and sells, Sats Stacker gives you the tools to track your progress and stay on target—without ever needing to link an exchange or share your personal data. Create Your Own Accumulation Plan Set up a custom Bitcoin stacking strategy by choosing how much you want to buy and how often—daily, weekly, fortnightly, or monthly.

Log and Track Your Bitcoin Journey Sats Stacker acts as your personal Bitcoin logbook. Every time you follow through on a reminder, your sats are automatically logged. You can also manually record additional purchases, sales, or transfers. The app calculates your total sats accumulated, your fiat invested, and the current value of your stack—with support for USD, GBP, EUR, AUD, and CAD. See Real Results and Projections Monitor your BTC stack’s performance over time with a simple view of your gains or losses, based on current market price. Use the built-in projection calculator to model your potential future stack: enter your recurring investment amount, time horizon, estimated BTC price, and any current holdings to see what your future stack could be worth. Live Market Data Keep an eye on the market with real-time Bitcoin price, market cap, and 24-hour percentage change—all from within the app. 100% Local, 100% Private Your data is stored securely on your device only—never uploaded, shared, or tracked.

Whether you're new to Bitcoin or a long-time stacker, Sats Stacker helps you stay organised, consistent, and confident in your journey. Note: Sats Stacker does not allow you to buy or sell Bitcoin.
