Bitcoiner

Bitcoiner pulls the signals a holder actually watches into a single, calm dashboard: live price and market stats, the Fear & Greed index, mining cost and network hash-rate, and futures long/short positioning.

It's built in React Native with Skia-rendered charts, aggregating public data from CoinGecko, Alternative.me, Binance Futures and mempool.space, and rounds out the market data with plain-language education on self-custody. Currently on TestFlight.
