Doesn’t work

This app seems to be a dud. It shows the screens but doesn’t fill them with any information. It doesn’t offer Apple Watch as a source, but it does offer phone. I selected that. But it didn’t draw from my Apple health. I tried to manually enter food as a test, but it just asked me to take a picture of my food. I set my weight in lbs , but it switched back to kg. Then the app was reporting that I joined 5 hours ago when it was only a few minutes. Now the app reports the accurate time but says my last update was 5 hours ago.

Wish could connect to Apple Watch

I was really excited to use this app but was disappointed when I found out it wouldn’t connect to my Apple Watch and there wasn’t an option for it. When I chose the phone option, I couldn’t find anywhere to log in any information.

I would so use this app if it could get all my information from my Apple Watch.
