Runees — treadmill run dashboard

What it is

Live run data from a Garmin watch, without extra hardware.

Runees connects a Garmin Forerunner to a live treadmill dashboard over Bluetooth LE. It shows heart rate, pace, cadence, distance, and timer in real time while you run.

When a session ends, the app writes a valid .FIT activity file — FileId, Activity, Session, Lap, and Record records — that imports into Garmin Connect, so treadmill runs stay in your training history.
