A park to run through

Treadmill Smart Speed has a second mode. Just Run records a treadmill run on your phone alone, with no Zwift, sensor or watch to connect. It is in version 3.1.0 on the App Store and version 1.1 on Google Play.

A park to run through

Choose Just Run at the bottom of the speed source list, set the speed to match the treadmill’s console, and start. A runner in orange, a man or a woman as you choose, runs along a path through a 3D park at the speed you set, and changes pace when you do, with the same buttons and presets as the rest of the app. If you would rather have the numbers alone, one tap puts the park away.

Every kilometre or mile has a gate. Run through it for your split, a tap and a burst of confetti.

Every run kept

Each run is kept on the phone with its time, distance and pace, and the last 50 are there to look back on. The distance is worked out from the speed you set, so the summary lets you enter the distance the treadmill showed at the end, and the run is matched to it. Then export the run as a TCX file, to share with another app or save. Delete any run you don’t want to keep.

Nothing to pair

Just Run uses no Bluetooth and asks for no permission. Its runs stay on your phone unless you export one. The privacy section for Treadmill Smart Speed covers Just Run on both versions.

Try it free

Just Run shares the free run with the rest of the app: every feature is free for a 10-minute run, with an hour between free runs, and a run is saved where the time ran out. One in-app purchase unlocks it for good. There is no subscription, no account and no adverts. If you bought the original paid iPhone app, Just Run is yours too, like everything else.

It needs iOS 17 or later on iPhone, or Android 14 or later.
