Sää & Sähkö (English name: Weather & Spot Prices) is an Android app for Finland that shows the Finnish Meteorological Institute (FMI) and Open-Meteo weather forecasts side by side, Finnish spot electricity prices and FMI weather warnings. The weather view compares the two forecasts for the next 24 hours, with a precipitation chart, a weekly forecast, the nearest FMI station's latest observation and sunrise and sunset times. The electricity view lists today's and tomorrow's 15-minute and hourly prices with a chart, colour-coded price levels and a VAT switch, and can notify you when tomorrow's prices are published. Warnings for your location are shown five days ahead, with optional background notifications. The interface is in Finnish, Swedish and English. There is no user account, no analytics and no background location. Source code, issues and discussions: https://github.com/jrs8205/saa-ja-sahko
