### 3/5 — Overall pretty good

*2026-04-26*

Provides what I need but it does not let you change your age if you make a mistake when setting it up. Which is annoying given that age is used as the basis for pretty much all of this. They also don’t respond if you contact them.

### 1/5 — User Beware - Security and Privacy Issues

*2025-10-06*

I have had several concerns and issues with this app over the week of my trial.

Most concerning is that after deciding to end my trial because of all the technical issues, I found that it does not have a log out option, a user account option, or a clear my data option. 

The app pulls in fitness data from “integrations” but it doesn’t push. 

The watch integration is non-existent. It only pulls data from an activity you run with the native watch app. So, if you are working out at the gym and don’t have your phone on you, but want to check your zones and points on your watch, you can’t.

After ending a workout and closing the apps the workouts continue to run on the background. 

If you use any other fitness app or workout system, this app doesn’t sync any of that data. (Ex: strava, or f45, etc.) 

Finally, I signed up for the trial, never selected to to be billed for the yearly subscription, and yet I was billed for the yearly subscription instead of monthly. No response from their support team. 

Based on this, my guess is it was pushed live as a “get-rich-quick” tactic by the developers and then sells the data harvested. The developers are likely counting on you not noticing the $4 a month charge.

### 1/5 — Garbage

*2025-04-07*

For $6 a month this app stinks. Keeps freezing up while in use. No metrics for the fat burn percentage of calories. Click on the support link from the app details takes you to a broken link file not found.

### 5/5 — Fat burn App

*2024-08-25*

Has been a great help!

### 5/5 — Update: Immediately crashes in 17.2/15 Pro Max

*2024-06-21*

So my workout activity broke my app 😂😂😂
Alex has been an absolute pleasure in helping to resolve my issue. Back in the game and loving the dashboard aspect. Cheers 🥂🥂🙃

Edit: Loved it previously to upgrading, now it immediately crashes.

**Developer response:** Glad we could get you working well again!

### 5/5 — Great app for weight loss!

*2024-05-24*

The only app that tells me exactly how hard to workout to lose fat. I love that I can import from the fitness app for my fitness+ workouts. Love the new leaderboards! Can you add ability to create my own group?

**Developer response:** Thanks for the review! We love user feedback, how can we improve? support@pkfitness.com

### 2/5 — Would have been 5*

*2024-03-20*

Great app. Gives great insight in to how the body burns fat, and how to maximise fat burn. 

However, it doesn’t seem to work with family share, so my wife and I are both expected to pay a subscription. 

I have emailed support twice, but received no reply in 3+ weeks. 

It is for that reason that I have only given 2*, app is great but support is poor. 

You need to sort this.

**Developer response:** Hey FatBurnerUK,
Our app does indeed work with Family sharing. Send us an email at support@pkfitness.com or give us a call at 626-335-6520 M-F 8am - 6pm PST. We would be happy to help you get sharing working. support@pkfitness.com

### 1/5 — Immediately crashes in 17.2/15 Pro Max

*2023-12-19*

Loved it previously to upgrading, now it immediately crashes.

**Developer response:** Hi Jae,
Is the latest update working well for you? support@pkfitness.com
