Treadmill Smart Speed 3.0 is on the App Store

Rebuilt from the ground up: your iPhone as a Bluetooth foot pod, with speed from the buttons, a Bluetooth treadmill, your arm or your Apple Watch. If you bought the original, it is still yours.

Set your speed, and Zwift sees it

Treadmill Smart Speed 3.0 is out on the App Store, rebuilt from the ground up. It turns your iPhone into a Bluetooth running sensor, so Zwift, and other apps and watches that read a standard foot pod, see your treadmill’s speed and incline.

Made to be read mid-run

The speed you are sending fills the screen, big enough to read at arm’s length, and every control sits within reach of a thumb. The speed moves in steps of 0.1, six presets are a tap away, and holding a preset saves the speed you are running at. Speed and pace each have their own choice of metric or imperial.

Four ways to set the speed

Match the treadmill with the buttons, which works with any treadmill or walking pad. Or, if your treadmill already talks Bluetooth (FTMS, or an iConsole+ console), the app reads its speed and incline and passes them on for you; it only reads, and never changes the treadmill’s speed or incline. Or strap the iPhone to your arm and let its motion sensor estimate the speed. Or run with the Apple Watch app.

The Apple Watch app is back

The Watch app from the original carries over, working with the new app. It estimates your speed as you run, and now sends your heart rate to Zwift too, whichever way you are setting the speed.

Bought the original? It’s yours

If you bought the original paid app, everything in this version is free for you, for ever. There is no subscription and nothing to restore: it is recognised from your Apple Account, on any of your devices.

Try it free

For everyone else the app is now free to download. Every feature is free for a 10-minute run, and one in-app purchase unlocks it for good. There is no subscription, no account and no adverts.

It needs iOS 17 or later, and the Apple Watch app needs watchOS 9 or later. In Zwift, look for your iPhone under its own name: iOS doesn’t let an app change the name it is listed by. The app’s help walks through pairing.

Questions, or something not working? Email support@appyappster.com and you will get an answer from the person who wrote the app. The privacy section for Treadmill Smart Speed covers both versions.
