♥️ This App

I asked Gemini for a free bio-age app and this is one of three that was suggested. I love it - it’s exactly what I was looking for. I would have given it 5 ⭐️, however, even though I have it set up to give my results in imperial measurements, some come as metric.

Update: After this review posted, Graeme the developer reached out with some questions so that he could make corrections. Everything is imperial except for some a couple results when I’m using the AI Coach for my weekly summary. Incredibly responsive developer, therefore I’m changing my review to 5⭐️!

Response from developer

Please reach out to me via email grae@mybioage.app and please share with me the results that still metric and I will fix them in the next update.

Decent free app, but laggy

Very laggy scrolling even on a new iPhone 17 Pro with latest OS. Make it faster and also maybe remind to take blood pressure or other missing data if that was recorded before but not taken in a while.

Response from developer

Will look at improving the scrolling and reminders for BP is coming very soon

Does what it says, but…

I was looking for an app that would approximate my biological age à la Whoop, without the price tag, and this app does just that. It seems like the team is just a solo dev, so thanks for developing a good app and releasing it for free.

My only gripe is that I wish I could interact with the AI. The templates are a good starting point, but I wish I could ask my own follow up questions. If I’m chewing up my memory to store the AI, I want to be able to use it more fully!

Incorrect

Sleep data is incorrect making the rest of the data incorrect.

Response from developer

Fixed in Version 1.0.22, thanks for the patience here.

Sleep data not syncing

Apple Watch sleep data is not syncing correctly with bio age….apple data averages 7.5 hours / night for pay 6 months. Bio age average is 5 hours. Is that low number affecting my bio age??

Response from developer

Fixed in Version 1.0.22, thanks for your patience here.
