### 1/5 — NOT FREE

*2026-08-11, version 2.1.22*

This app requires a membership.  It is NOT free

### 1/5 — Bad

*2026-08-10, version 1.5.9*

Bad

### 3/5 — Apple Watch Option?

*2026-07-31, version 2.1.22*

Is it an option to use this app on your Apple Watch? It’s a great app but it’s not connecting to my watch or I can’t sync my Spotify as advertised

### 3/5 — I would love an Apple Watch app!

*2026-07-25, version 2.1.22*

Great app. Does exactly what I need except also show up on my Apple Watch. I’d love to be able to start, stop, pause from my watch when my phone isn’t accessible. The phone is great when I’m doing solo workouts. In group classes we often do portions of workouts at our own pace and I’d love to have the app counting and tracking for me during those too.

### 5/5 — Great workout timer

*2026-07-19, version 2.1.22*

Has lots of customization and preset workouts. 1 week free trial and then lifetime access option that is pretty affordable.

### 5/5 — Been using this every day for the last couple years

*2026-07-08, version 2.1.22*

I have at least 75 made up workouts that I use on a daily basis. This app is fantastic. Couldn’t live without it🙌🙌

### 1/5 — Paid entry

*2026-07-08, version 2.1.22*

Booooo, let’s you download to immediately show you a paywall

### 5/5 — Excellent

*2026-07-06, version 2.1.22*

Easy to use, took me 5 min to put an entire routine into it. Well worth the cost

### 1/5 — Charged for a free trial

*2026-06-05, version 2.1.22*

I signed up for a free trial, canceled before it ended, and was STILL charged $27.49 for the subscription! Apple reversed it because I disputed it, but that is a shady business practice. Do not trust them!

### 1/5 — Staff prompting for review reviews

*2026-05-26, version 2.1.22*

Stop prompting for reviews
