### 1/5 — Dev has no faith in his app

*2026-01-12*

and as a direct result, you can see NOTHING without first committing to a 3 day trial. That mentality tells me all I need to know. Way too many competitors in this niche to tolerate such blatant, uh, donkey dust. Uninstalled.

### 1/5 — Premium required

*2025-02-13*

The fact that I can’t access the app without selecting a renewing premium means I won’t use the app.  The slider to “enable 3-day trial” does nothing.

### 5/5 — Great app!

*2024-12-21*

I’ve tried so many fitness apps but Treadly really stands out. It’s incredibly easy to use and the real time heart rate tracking. Let me see exactly my ideal zone. The step counter is super accurate and I love how it breaks down zone two and zone five giving me insight I’ve never had before.

### 1/5 — Fix it.

*2024-10-25*

Clock is way behind.

### 5/5 — Great Change of Pace

*2024-09-29*

I’ve been enjoying how this app gave me a different perspective to my workouts as I focused more on locking into specific zones. It has created new challenges, not only with maintaining a zone but transitioning from one zone to the next and figuring out how to dial it in.

### 5/5 — So good!

*2024-09-02*

This app is VERY easy to use. Super helpful, since I need all of the guiding it has to offer. I work from home, so tracking my movement is important. This helps a great deal. Already recommended to a friend!

### 5/5 — Great app!

*2024-08-27*

This year, I wanted to get in the habit of working out more during the week. The app has been a vital tool in helping me plan my workouts, stay consistent with my schedule and even help me work towards more flexibility and mobility. Treadly made it possible to get in that habit by giving me more in-depth insights about my health and progress.
