### 1/5 — Useless app

*2025-02-05*

Does not provide any insights to why my biological age is going up or down.

### 3/5 — Not for cyclists

*2024-12-22*

Great app if you walk or run. But cycling or other workouts it doesn’t consider so don’t expect to be called younger if that’s what you do.

### 1/5 — App doesn’t work

*2024-08-27, version 4.3.2*

App doesn’t work. Tried several times to upload my data but it stops and freezes half way.

### 2/5 — Ok app, unreliable health kit sync, no support

*2024-05-04, version 4.3.2*

I like the idea of this app but cannot give it more than two stars due to unreliable syncing of healthkit data, which drives it's predictions and negatively impacts the users ability to make meaningful changes, and large battery impact. Also, support is non-existent with requests going unanswered for more than a week.

Update: 4/2024

Still having problems with data syncing from HealthKit.  Time to abandon the app.

### 4/5 — Good idea and UI but…

*2024-05-01, version 4.3.1*

Not very clear how precise this biological age estimate is and what to do with this information. My biological age is almost identical to chronological. Although looking at the history it seemed to be higher during COVID but that’s perhaps because I was sitting at home so no steps were counted

### 4/5 — Good idea

*2024-04-20*

I like the idea and happy to help to deepening our understanding and knowledge around aging. 

It doesn’t seem like the app is fully leveraging all the data available through Health app. It’s just grabbing heart rate and steps.  There is lots available that I think would make any AI model more powerful such as blood pressure, weight, exercise details, glucose, vo2max, sleep, etc.  the fact that weight is set just as an input value during initial setup but doesn’t pull from Health seems like a miss. Certainly not everyone has other devices that contribute these data values into Health for this app to leverage. However, many of us do so the ai model should be flexible to calculate on a wide range of attributes and perhaps become more meaningful as the number of attributes increases.  If you are going to pull data from Health, why just 2???

### 3/5 — No data

*2024-02-06*

It says on the program. Check back in a few days for results. But I have and still nothing. I have since downloading the app have had some runs and a couple of workouts and nothing shows

### 5/5 — It's great

*2023-12-26, version 4.1.0*

I'm always looking for motivation to take care of myself. I'm 49, but my biological age is 46. As I bring that number down, it will be even more motivating.

One suggestion would be that getting to bed early is worth far more than getting 8 hours sleep.
If I sleep at 2am and get 10 hours sleep, my HRV always shows my heart is struggling.
But going to bed at 10, sleeping 6 hours, my HRV shows perfect. 

Thank you so much for this wonderful app!

### 5/5 — Very accurate

*2023-11-26*

Highly recommend

### 5/5 — Predicts more than just biological age

*2023-11-22*

This app quickly loaded my health data and gave me useful predictions of my biological age, my resilience (recovery time from stress), and my position on the biological age distribution.

I’d love the addition of more metrics!!
