Treadmill Smart Speed is design to communicate your Treadmill Running Speed from you iPhone or Watch to a receiving devices. It used the same Bluetooth communications protocols as expensive running footpods. You choose your preferred Speed Input: 1 - Select the speed your treadmill is moving on the app and this is transmitted via bluetooth to your receiver. (This is my personal recommendation) 2 - Attach the iPhone security to yourself and run. The iPhone's motion sensor will estimate your speed and transmit this to your bluetooth receiver. ****** iPhone 5S and above. ***** (fully dependant on accuracy of iPhone) *****THIS OPTION WILL BE DISCONTINUED IN FUTURE VERSIONS, PLEASE RELY ON TREADMILL MODE OR WATCH MODE 3 - Use your phone in combination with your Apple Watch. The Watch will send Speed, Cadence and Heart Rate via your phone and transmit these to your bluetooth receiver. (Watch workouts can be saved as part of your daily activity rings) (fully dependant on accuracy of Watch) *New Feature :you can control the speed manually using the crown, simply tap the digital speed to enable/disable. Notes: • TSS Watch Module - requires an Apple Watch to calculate Heart Rate, Cadence and Speed data. • TSS Watch Module integrates with the Health App on your iPhone to contribute to your Activity Rings. It will request permission to access the relevant data types associated with a workout. *Connection to MAC Requires BLE 4.0 - The Mac mini , MacBook Air were both updated with Bluetooth 4.0 support in 2011. The MacBook Pro Mac 2012. The Mac Pro in December 2013. ## Key features - Transmit treadmill speed via Bluetooth - iPhone motion sensor speed estimation - Apple Watch speed, cadence, and heart rate transmission - Manual speed control via crown - Integrates with iPhone Health App - Compatible with BLE 4.0 Macs ## Recent user reviews (10 of 57) All indexed reviews: https://appshunter.io/ios/app/treadmill-smart-speed/id1193076459/reviews.md ### 5/5 — This is working fine as of Nov 2024 *2024-11-03, version 1.45* The problems reported in earlier reviews about not working with Zwift appear to have been fixed - I bought it today and it works fine. ### 5/5 — Life saver *2024-05-06, version 1.45* can use any treadmill and have fun on zwift. Please never change this app ### 2/5 — Doesn’t do what I want *2024-01-26, version 1.45* 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. ### 1/5 — Dosent work *2023-12-12, version 1.45* Just purchased dosent show up on my iPhone under Bluetooth on zwift as of 12/12/23 all devices currently upto date. ### 5/5 — 反応が遅い *2023-11-23, version 1.45* iPhone arm band モードで腕を振り始めても、反応するのに8秒〜10秒かかります。腕の振り始めから反応できるように改善いただくと嬉しいです。よろしくお願いいたします。 ### 5/5 — It Worked Great for me! *2023-08-05, version 1.45* 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. ### 5/5 — Perfect solution to a frustrating problem *2023-05-23, version 1.45* It’s little apps like this that still add value to the App Store experience. Small developers creating solutions that big companies overlook or don’t want to implement. Had a small issue understanding the setup process so contacted the developer who was only too happy to provide a detailed walkthrough which actually worked. It’s only a few dollars and provides a simple solution that would otherwise need expensive hardware purchase. Highly recommended ### 2/5 — Zwift issue *2023-02-05, version 1.45* Used to work fine for me with Zwift and that was very convenient. However it does not work anymore since a few days. I can pair the app in zwift but the speed is not detected so my character is not moving. Please fix it! ### 5/5 — Top App! *2022-08-17, version 1.45* Works great with Rouvy as well. ### 3/5 — Has stopped working with zwift *2022-05-11, version 1.45* This worked really well with zwift running but recently stopped. Maybe due to a zwift update? ## Frequently asked questions about Treadmill Smart Speed ### What does Treadmill Smart Speed do?
