We fetch real-time prices directly from 5 major exchanges: Bitstamp, Kraken, Coinbase, Gemini, and Binance US. The "Average" price is calculated from all visible exchanges.
Each exchange operates independently with its own order books. Price differences (called arbitrage) occur naturally due to varying liquidity, regional demand, and trading fees.
Yes. Fast Bitcoin is on the App Store for iPhone, iPad, Mac, Apple TV, and Apple Watch.

Fast Bitcoin sends only the data that alerts and subscriptions need: your alerts, your notification settings, and your App Store transactions (through RevenueCat). Display settings stay on your device. We do not use advertising trackers, collect wallet addresses, or sell your data. See our privacy policy for details.
