What SpeedLab35 can do
GPS-verified, not guessed
Every run uses live GPS data with accuracy and satellite readouts and G-force sensing. If the signal drops, the app flags “GPS LOST” instead of hiding it.
Speed and distance modes
Time any speed range, such as 0-60 mph or 0-100 km/h, or run 1/8 mile, 1/4 mile, 1 km and 1 mile presets. Switch between km/h and mph at any time.
Road grade check
A downhill run can flatter your time, so the app checks the road and flags the steepest grade on your route, with the place.
A video of every run
Get a vertical 9:16 video with a live speed graph, a G-force gauge and a data strip with GPS accuracy, satellite count, altitude and time, ready for Shorts, Reels and TikTok.
A recap after the run
See your time, speed curve, road conditions, split times, acceleration profile and run stats in one clip.
