Stratum is a Bitcoin-first watchface for Pebble Time 2.

Designed for Bitcoiners, it puts the information you check most often directly on your wrist: BTC price, sats per fiat unit, fee pressure, weather, forecast, battery status, update age, block height, hashrate, and difficulty.

The layout is intentionally dense, featuring a large time display, fixed date rail, prominent price section, and configurable data panels. Everything is optimized to maximize information without sacrificing readability.

Customize Stratum with color themes, fiat currencies, refresh intervals, number formatting, weather units, fixed weather coordinates, sidebar widgets, and lower panel layouts.

BTC price data can be sourced from CoinGecko, Coinbase, Blockchain.com, or a custom JSON endpoint. Bitcoin network statistics and fee estimates are sourced from Mempool.space. Weather data is provided by Open-Meteo.

Inspired by TimeStyle. Built for Pebble. Tuned for Bitcoin.
