### 5/5 — Useful Fitness App

*2026-07-23*

Love it. I enjoy statistical analysis and this app scratches that itch.

### 5/5 — Data not being read

*2026-06-24, version 446*

The last update has removed the sleep data from the front page. When digging deeper the app reckons that I have slept for a minimum of 24.5 hours every day. This has made the app useless.
UPDATE: The app has started to read sleep data again and seems to be fairly accurate. Not sure what went wrong, but I did nothing then it started reading again. Hence the upgrade to 5 stars.

### 1/5 — Not working as of late

*2026-05-28*

New update won't move past "preparing" page after a day or so. Completely broken for me.

**Developer response:** hey looks like you found a bug 🐞 remove and reinstall the app - should work! If not - drop us a message support@bodyinsightsapp.com

### 3/5 — Buggy

*2026-05-23*

I get very different values with the age and fitness components, sent screen shots and got the not very helpful response that it’s a bug but no offer for a refund. Starting in May 2026 the app keeps pushing to upgrade to the premium version which I already subscribe to. I delete it, redownload it and it works for a day or so before asking for the upgrade. 

5/26/26, thanks for the app update, it fixed the problem.

**Developer response:** Hey there Anthony, 
I understand that this is a very frustrating upgrade loop bug. When the app gets in the way of you tracking your health, it defeats the whole purpose, and I understand your disappointment.
As soon as I saw your message, I found the bug and released a permanent fix the next day. If you update the app now, it will recognize your premium subscription smoothly.
Regarding your refund: because transactions happen securely through the App Store, Apple handles all payments directly and developers cannot issue refunds. You can easily request a prorated refund from them at reportaproblem.apple.com.
If you choose to give the updated version another try, I’d love to know if everything is finally working smoothly for you.

### 2/5 — Buggy

*2026-05-19*

I get very different values with the age and fitness components, sent screen shots and got the not very helpful response that it’s a bug but no offer for a refund. Starting in May 2026 the app keeps pushing to upgrade to the premium version which I already subscribe to. I delete it, redownload it and it works for a day or so before asking for the upgrade. I want my money back, prorated is fine but this has been very disappointing.

### 5/5 — very succinct and glanceable, yet detailed when you dive in.

*2026-04-20*

a very pleasant view of a lot of detailed health data. I like that it presents as glanceable - yet informative, but there’s plenty to dive deeper into when you have the time. good selection of widgets with the same pleasing, glanceable info.

i use this to gauge when i can push and when i should hang back and it has been surprisingly spot on! i have had this app for a while, but due to such accurate consistency, i decided to subscribe.

——
i have found a bug though..
Under the Fitness > Heart section, the RHR shows “Your current resting heart rate is outside standard bands” with a question mark icon if your resting HR is under 46. As an athlete, mine is at the 41 range on average. so maybe increase the that to incorporate a larger range?

**Developer response:** hey there, looks like you're the outlier in the data and have exceptional heart health! Great to hear that! I've added another tier for people like you so you can know now that you're better than 99% of population haha 😁

### 3/5 — Strange behaviour

*2026-03-31, version 411*

Ths thing is way too battery hungry even with background refresh disabled. Upwards of 24% usage on a brand new iphone17 with screen time of a few minutes. Kinda confused as to what its actualy doing to warrant this.

### 5/5 — Perfect for us chronically ill peeps

*2026-03-27*

This is the app I’ve been needing. I have an Apple Watch, but had been considering getting a wearable through Visible to help with pacing. Now, I don’t need to do that. 

Body Insight has all the information I need to make sure I’m pacing myself properly to avoid a flare. Super affordable subscription too!

The only thing missing that I wish it did… show insights from my glucose testing. I don’t have a CGM, but stick test frequently.

**Developer response:** Hello Morgannin, thank you so much for sharing this. It truly means a lot to hear that the app insights are making a real difference for you.

I actually started building this app for that exact reason -- I was navigating my own chronic lyme and felt that traditional medicine was often missing the bigger picture by completely ignoring signals our bodies send us every day. I wanted to create something that finally listened to that data, and I'm so glad it's helping you find a rhythm that avoids those flares.

Your suggestion about manual glucose entry is a really thoughtful one. App should actually "catch" glucose data if it's there. Can you drop me a message j@bodyinsightsapp.com so I can investigate why it does not show for you?

### 1/5 — Used to be good and simple

*2026-03-22*

This app is getting to be more cluttered and chunky

**Developer response:** Hello, you're right to point that out - app WAS getting clunky UX wise. So I sat down and spent the last couple of weeks working to strip away that "clutter" and simplify the experience so it feels light and intuitive again. If you update the app now, you'll see a much cleaner space designed to let your data speak for itself. 

I'd love to know if it feels right to you now.

### 5/5 — Useful Fitness App

*2026-03-12*

Really enjoy this app.
