## Most critical reviews (10 lowest-rated)

### 1/5 — Stopped working

*2024-03-25, version 1.3.5*

App has stopped working can’t login no response from support

### 1/5 — Video doesn’t rotate or enlarge

*2023-01-11*

Neither on phone nor on iPad. Very irritating and poor quality for a paid subscription product.

### 1/5 — Cancel Monthly

*2022-09-07*

No way to cancel the monthly charge that I signed up for - no Response from numerous requests to the company - BAD customer service

### 1/5 — Not sync’d

*2021-02-21, version 1.2*

Requires a lot more thought. Voice intermittently not sync’d with movement

### 2/5 — Great work outs, the sound is terrible

*2021-07-09*

I really enjoy the workouts but the sound is not always aligned with the videos, it jumps back a few seconds. Please fix this because people pay a lot of money for the app.

### 4/5 — Provides another approach to a core workout

*2021-04-05, version 1.2*

I’ve had one for 6-9 months now. Often do two workouts back to back to get a 30 min blast. Provides variety and is a good combination of a hiit and core workout. Gets the heart rate up while working the core in a closed kinetic chain fashion. Enjoy doing a weekly nucleus core pro workout.

### 5/5 — Happy at home user!  👍👍

*2022-11-03*

I’m happy with this app and very excited to get more access to training videos. I simply use my phone’s screen mirroring function to watch in my living room smart TV.

### 5/5 — Rehab Workout

*2022-09-04*

I had the misfortune of tearing my rotator cuff, my labrum, and my bicep, and am 2 months into rehab. I also travel and was looking for a convenient exercise device I could take on the road. I ran Nucleus by the PT, got a thumbs up, and have been using it for two weeks. Loving it. Nucleus has all the exercises I need to slowly but surely strengthen my shoulder and keep me in good cardio condition. I’m looking forward to a lasting and healthy relationship with Nucleus.

### 5/5 — An absolutely great addition to your workouts.

*2022-03-28*

I love this for ten minute workouts!! It gets my blood pumping and makes my arms feel like they’re firming up!  

I’m glad I purchased it!!

### 5/5 — The best way to  start 2022!

*2022-01-09*
