A clean black-and-white watchface that puts rainfall front and center: today's forecast precip and the last 24 hours of actual rainfall, from your own Weather Underground station.
Also shows time, date, location, current temp, high/low, and a status bar with Bluetooth, battery, and a freshness counter.
Setup: Enter your Weather Underground API key and station ID in the watchface settings.
Requires a free WU PWS account.
