Rebuilt from the ground up: a speed readout you can read mid-stride, six presets, incline and Apple Watch support. Bought the original? It stays yours.
Your treadmill, on Zwift.
Treadmill Smart Speed turns your iPhone into a Bluetooth running speed and incline sensor. Set the speed you are running on screen and your iPhone broadcasts it, exactly as a footpod would — so Zwift, and any other app that reads a running sensor, sees your treadmill. No footpod, no treadmill upgrade, no extra hardware.
GETTING CONNECTED
1. Start pairing in Zwift. Open the pairing screen and choose the run speed sensor slot.
2. Look for this iPhone by its own name. The app cannot change how it appears — to change what Zwift shows, rename the phone in Settings › General › About › Name.
3. Wait for the pill to turn green. It reads Connected once a fitness app is receiving speed. Until then it reads Discoverable.
BUILT TO BE READ MID-RUN
The screen is made to be read at arm's length, in a dim room, while you are running. The speed being broadcast owns the display, and every control sits in the half a thumb reaches.
• A large speed readout with your current pace beneath it
• Plus and minus keys that step in 0.1 increments
• Six presets you set to your own paces, one tap each
• Incline, sent alongside speed
• Metric or imperial, chosen separately for speed and for pace
• Keeps broadcasting in the background, so glancing at another app does not drop the connection
APPLE WATCH
The Apple Watch app estimates your speed and cadence from your wrist and reads your heart rate, then streams them to your iPhone. Your iPhone broadcasts the speed, and your heart rate as a heart-rate sensor that Zwift can pair too. Your run is saved to Health as a workout.
IF YOU BOUGHT THE ORIGINAL APP
It stays yours. Everything in this version is free for you, for ever — no subscription, nothing to restore. It is recognised automatically from your Apple Account, on any of your devices.
FREE TO TRY
Every feature is free for a 10-minute run, with an hour between free runs. When a free run ends, the speed sent drops to zero until you unlock.

I set a speed of 2 in the app but my avatar in game shows 1.5. I’ve tried switching between imperial and metric but even when app and game both are set to miles the speeds are way off.
It Worked Great for me!
Walkin Still
For $5 I’m now able to walk on Zwift!Do to mobility issues I find it very difficult to walk over 1 mph. This means normal trackers have not worked for me on Zwift. By being able to manually control to speed information transmited to Zwift I was able to get my avatar to slowly move around Watopia. This is huge for me. Thank you. If you have similar issues getting onto Zwift I highly recommend giving this a try.
Doesn’t do what I want
Prooftheory
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.
Solved the biggest problem running in Zwift.

I love running on Zwift and it has made an incredible impact on my running, but I get so frustrated with the footpod, and even the new treadmill attachment. They dramatically understate or overstate my speed, and get further and further off as the run goes on. I was actually going to buy a new smart treadmill so that I could get consistent numbers when I found this. That has been so helpful and saved me a ton of money.
Treadmill Smart Speed has been completely rebuilt.
• A speed readout sized to be read at arm's length, mid-run
• Six presets you set to your own paces, one tap each
• Incline, sent alongside speed
• Metric or imperial, chosen separately for speed and for pace
• The Apple Watch app, carried over and working with the new app, now sending your heart rate to Zwift too
