### 1/5 — Not Good

*2025-05-24*

This app is worthless. Don't spend money on it

### 5/5 — Helps a lot

*2025-05-03*

I do cross country and I used to run kinda slow + I couldn’t run any longer than a mile, but this actually helped a LOT (especially with distance) :)

### 5/5 — New Runner

*2025-04-24*

I am brand new to this app but love it so far!

**Developer response:** Thank you so much! We're thrilled you're enjoying the app — more great updates are on the way!

### 1/5 — Doesn’t work on Apple Watch

*2024-09-23, version 4.0.2*

It doesn’t work on Apple Watch

### 3/5 — Good but glitches

*2024-07-10, version 4.0.2*

Very simple and easy to use - when it actually works how it should. I’d probably say every 1 in 5 times I use this app it decides to pause and stop the timer which I can’t seem to get going again, so I’m fumbling with the app whilst I run, which completely throws me off for the rest of my run. Apart from that the app is good, it’s accurate with pace and distance but just needs these glitches fixed.

### 5/5 — AMAZING

*2024-07-08*

Finally I can set up my apple watch running training from the phone and not loosing time from my watch. Amazing job

**Developer response:** Thank you so much!

### 5/5 — Alex

*2024-04-15*
