Rowlink

Rowlink is a web app for Yosuda rowing machines that connects directly to the rower over Web Bluetooth, replacing the FED Fitness app. It shows a live dashboard with pace, time, distance, stroke rate, power, and calories, runs guided interval and benchmark workouts, and saves every session in the browser with charts and export to FIT (for Garmin Connect and Strava), TCX, CSV, or JSON. There is nothing to install and no account; everything stays in local browser storage.

Rowlink includes intervals, benchmarks (500 m, 2000 m, and 20 minutes), steady rows, a pyramid, and 27 classes modeled on the FED app’s rower classes, with pace targets that scale to your own reference pace. Any workout can be copied and edited, or you can build your own from row and rest segments.

The app is plain HTML and JavaScript with no build step or runtime dependencies, including its own FIT file encoder. It works on any platform supporting Web Bluetooth such as Chrome or Edge on Android, Windows, macOS, ChromeOS, and Linux, but not on iOS.
