Supported now
Mac
macOS 10.14 (Mojave) and above. Works on both Intel and Apple Silicon (M1/M2/M3/M4). The app connects directly to your Bluetooth trainer.
Recommended: MacBook or iMac running macOS 13 (Ventura) or newer for best Bluetooth stability.
iPhone & iPad
iOS 16 and above. Use WattLog.pro without a laptop at all — the app connects directly to your trainer over Bluetooth.
Android
Android 9.0 (Pie) and above. The app connects directly to your trainer's Bluetooth — no laptop required.
Coming soon
Windows PC
Windows 10 (build 1903) and above. The Windows native app is in development — sign up to be notified when it launches.
Linux
Ubuntu 20.04 LTS and derivatives. The Linux app will use BlueZ for Bluetooth. ETA depends on demand — if you're a Linux cyclist, let us know.
What about Apple TV or Chromebook?
These devices currently don't support the native app WattLog uses for Bluetooth. We're investigating options, but there's no ETA — the gap is the Bluetooth connection.
If your setup is unusual, drop us a line — we'd rather know what people actually have than build for hypothetical users.
Can I use it in a browser?
Yes — there's an optional web interface at app.wattlog.pro that runs in any modern browser (Chrome, Firefox, Safari, Edge) for reviewing your data. Connecting a trainer over Bluetooth still happens in the native app.
Recommended: Chrome 110+ or Safari 16+ for best performance.
