General bug fixes

User reviews

The app we needed for ME/CFS

I’m really pleased that there is a decent app now that uses the Apple Watch to help determine energy usage levels. The developers are working on improving the app continuously and I’m so glad to see constant improvement.

Has a lot of potential

It’s a great idea. However, the dashboard needs work. It is very overwhelming and confusing with all the options. It really needs to be simplified or be able to hide some things. Also logging the daily assessment is a little confusing. It seems like the am pm options would be different but they end up being the same measurements despite changing them for each.
