Minor bug fixes

User reviews

Wish it worked!

UI is pretty confusing. Check-ins I thought I submitted are not submitted and are actually at default values. Not really getting the notifications to check-in either and when I do they’re not at the times I set them to be. I’m only three days into this so maybe there’s a learning curve here but I wish it was easier to figure out as I really do want to like this app. ETA: Having issues getting my data to sync as well. Have disconnected and reconnected 2x over—the first time because the values were just straight up wrong, the second time because they simply weren’t showing up at all. And I have a banner telling me to update when I’ve already downloaded the most recent update. Really want to like this but as is it’s useless—it doesn’t sync!

Fantastic app, new but promising!

I’m only a week in and so far love the app! It’s new so they’re still working out kinks and adding features but it’s basically like the popular wearable band but you get to use your device of choice! I’m using an older Apple Watch so I don’t get many all of the metrics but it’s been so helpful for me with pacing and seeing my data to match- looking forward to sharing with my medical professionals as well. Their team has been incredibly responsive and opened to feedback in real time it’s really cool to see and be a part of helping shape the app as well! I will come back and update in a few months on how it’s progressed and once all of the features unlock for me. (it spends anywhere from 7-30 days learning about you from your Data, which is amazing) well worth the wait! Thank you, developers for creating this app for us chronically ill folx! Exactly what I was looking for!

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.
