Wattsoever: Indoor Cycling Without the Cloud

Editorial interest 84/100 Selection signal · not a rating of the site

A free local app for BLE FTMS smart trainers, combining ERG workouts with GPX-based mountain-route simulation.

Landing page captured for the 2026-09-02 issue.

Field notes

Wattsoever separates structured ERG training from route simulation: workout files define targets, while GPX elevation drives simulated gradient and speed through the rider's watts. The site says each session is stored as 1-Hz samples in a local SQLite database alongside a FIT file, with NP, IF, and TSS calculated on-device. It lists support for ZWO, MRC, and GPX inputs, and presents Windows, macOS, and Linux builds as part of the planned first release.
