What's New in Treadmill Smart Speed

3.1.2

October 30, 2026

If you bought Treadmill Smart Speed back when it was a paid app, this update recognises your purchase again: everything is unlocked for you, for good, with nothing to buy. Versions 3.0 and 3.1 showed some of those customers the free-run countdown by mistake. Sorry about that, and thank you for staying with the app since the start. If the app still shows a countdown after updating, open Help and send the line beginning "App Store record" to support (Help › Support).

Works Great

I have been using the app for a few years on an iPhone/Apple Watch with no issues pairing to Zwift on an iPad; Apple TV or MacBook. Best $10 I have ever spent on an app. Love the new Interface. Much easier to customize and having the Apple Watch heart rate accessible while manually setting the speed is awesome; no need for an annoying chest strap when your already wearing the watch.

This is working fine as of Nov 2024

The problems reported in earlier reviews about not working with Zwift appear to have been fixed - I bought it today and it works fine.

Life saver

can use any treadmill and have fun on zwift. Please never change this app

Doesn’t do what I want

I was hoping the app would allow me to send the correct pace from the treadmill to Workout rather than relying on the terrible gyro guestimator that Workout uses by default. This app doesn’t do that. Rather it lets you use your phone to display the bad pace data from the watch as though that would somehow be more helpful than the display on the treadmill. I guess if you had a treadmill with absolutely no display, it might be better than nothing. I have nothing to say about the broadcast to zwift functionality as I didn’t use that.
