One-Line Flow:
An actually-good, open-source weather app for iOS + Android with pro-level data, radar, Vision Pro support, and zero ads — install it and enjoy feeling morally superior to everyone else.
OSS Weather
Open source weather app for iOS and Android
Clean UI. No tracking. No corporate nonsense.
Just real weather — powered by serious models, a one-man French dev, and your inner need to avoid bloated apps.
Direct Downloads (Pick your poison)
iOS (App Store): https://apps.apple.com/sa/app/oss-weather/id1499117252
Android (Play Store): https://play.google.com/store/apps/details?id=com.akylas.weather
F-Droid (IzzyOnDroid): https://apt.izzysoft.de/fdroid/index/apk/com.akylas.weather
Multi-Source Weather Data (Your choice, your chaos)
Runs on OpenWeather, Open-Meteo, or Météo-France.
Open-Meteo = free forever, no keys, no limits.
OpenWeather = free tier cries at rate limits.
Pick wisely.
Hidden Technical Flex (Nerd bonus)
Built with NativeScript, not your usual React Native/Flutter duet.
Includes ECMWF IFS HRES 9 km & AIFS 0.25° data models — the expensive European stuff pro apps hide behind paywalls.
Radar That Actually Moves
Powered by RainViewer — animated radar with past 2 hours + 30-minute forecast.
No static JPEG pretending to be “live weather.”
Vision Pro Ready
Yes… your Apple Vision Pro can check rain too.
Supports visionOS 1.0+.
The Lone Wolf Dev
Made by Martin Guillon (Akylas) — OSS purist, French, allergic to closed-source anything.
Support him if you like devs who don’t sell your soul: PayPal.Me
Minutely Forecasts
Minute-by-minute precipitation.
Forget “hourly.” This is “will it rain in 6 minutes?” energy.
API Key Drama (and the escape hatch)
Ships with a default OpenWeather key, but it hits limits faster than your WiFi at a wedding hall.
Switch to Open-Meteo to avoid this circus completely.
Missing Features (Don’t cry)
No weather alerts.
No Beaufort wind scale.
Widgets coming “end of year” (dev said this in June 2025, so… inhale hope, exhale patience).
License & App Size
MIT licensed — fork it, build it, sell it, tattoo it, whatever.
Android: 12.9 MB
iOS: 85.3 MB
Actively Updated
143+ workflow runs, updates as recent as July 2025.
Sometimes the guy pushes multiple releases per day — respect the grind.
The “NonFreeNet” Tag
F-Droid slaps a warning because it talks to proprietary weather APIs.
The app itself is fully open — the data sources aren’t.
Welcome to weather tech.
OSS Weather (Summary)
Clean. Fast. Open source.
Radar that moves. Vision Pro support.
Better weather models than half the paid apps.
And built by one guy who refuses to quit.
Install it → feel smug → enjoy the rain.
