The new weight tracking feature and Trends tab make it super easy to see my progress over time. The graphs look sleek, and the smooth animations and haptic feedback make the whole experience feel really polished. I also love that I can now track my heart rate using my AirPods Pro 3 without needing an Apple Watch. The settings are much more intuitive, zone training is easier to understand, and I can finally switch the app to Chinese! You can really tell how much work has gone into this update. Bugs have been fixed, the design is cleaner, and the whole app feels much more professional. Definitely worth checking out! ### 3/5 — Overall pretty good *2026-04-26, version 1.10.4* 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. **Developer response:** Hi, sorry for the bad experience! Our latest update should address this problem. Your age is factored into your max heart rate, and the new settings panel for your zone allows you to reset your age (DoB), and it’s much clearer how it works with the zone formula. Let me know your thoughts from the feedback button! ### 1/5 — User Beware - Security and Privacy Issues *2025-10-06, version 1.10.1* 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. **Developer response:** Hi, thanks for your feedback! We have made some big improvements which should address those concerns of yours. We've added a button to erase ALL your app data in settings. To be clear our app does not ask you to make any online user account, so since you don't log in, there is no "log out". And we certainly have NOT been harvesting your data for any type of sale. Your data stays private, not just anonymous, because it's saved securely in your iCloud which can only be accessed on-device. Currently our free trial is only available from the yearly billing option, so that's probably the source of the confusion around the monthly/yearly selection. The app's watch integration is purely optional, but it does include an Apple Watch app. You can get real-time zone training by either using the watch app or starting a workout from the iPhone app with any other compatible heart rate sensor. Alternatively you can record your workout on another app that supports Apple Health and this app will score those workouts automatically after completion. Any workouts you save with this app will be pushed to Apple Health, and likewise the app reads other apps' workouts from Apple Health. We aim to serve as an open part of the iOS fitness data ecosystem. ### 1/5 — Garbage *2025-04-07, version 1.10.1* 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, version 1.9.6* Has been a great help! **Developer response:** Awesome to hear Gary, thanks for the review! We love user feedback, let us know how we can improve! support@pkfitness.com ### 5/5 — Amazing APP *2024-08-22, version 1.9.6* This APP was extremely well thought and developed , it helps me so much to stay focus and to achieve attainable objectives **Developer response:** We appreciate the review! Love hearing how the app is helping you stay focused and achieving your objectives! support@pkfitness.com ### 5/5 — Fantastic App. *2024-08-15* Great app if you want to be motivated to get your steps up for the day whilst keeping in the fat burning zone. ### 5/5 — Update: Immediately crashes in 17.2/15 Pro Max *2024-06-21, version 1.9.5* 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, version 1.8.3* 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 ## Frequently asked questions about Weight Loss Tracker & Journal ### What is the Fat Burn in Zone 2 app?
