The first day I got this app and installed on phone and app watch series 2. It worked great. But starting day 2 and every day now for a week it crashes when opening app on my watch. I have to delete and reinstall the app on my watch several times a day. This is very very annoying. Plus I have noticed chunks of data missing due to app on watch and app on phone not syncing. My phone app will show heart rate and incorrect info, showing last update to be hours up to a day behind what the app on my watch says. Please fix this so I can enjoy the app. Other than that the app has many great features. It would be nice if I could actually use them.

I like the layout and the data idea. But the data was WRONG. Said I was sleeping 12 hours most days and my other apps were following perfectly. A few heart readings were Way off also. I don’t trust ANY of the data because of all the errors.

I haven't been able to use this app in weeks, maybe over a month. It gives me the 'Still working...' message and never opens up. Used to be 5 stars, but it's now a dead app, so it gets 1 star.

Everything what I am looking for my health condition. I am amazed what your app does? It gives me a brief summary of my cardio and works every 5 min. update. I love it!

This app was great because I could see all my past data. Now, it only shows mine one day. As far as I can tell, two years worth of data disappeared with the latest update. When I use the calendar to see past dates, everything is blank.

For no apparent reason, this app uses almost a gigabyte of cellular data every month even with cellular data turned off in the iPhone settings. This tends to use up my data when wireless or Bluetooth should do the trick (unless this app is constantly sending my data back to your servers.

Bought the Apple Watch for my son to track HR for seizures. We were shocked to find his HR was dropping and not elevating inadvertently this Watch may have saved our son from an unknown condition. Pros : I can “sometimes” write a note why his rate is elevated. The graph is better than the heath kit at telling me times and how long the rate changed. Cons: Needs to have an alarm for low heart rate Needs to have an edit button on any point of the chart (it’s really sporadic) that is really annoying. My sons HR was at 180 didn’t allow me to write a note but it elevated from 99 to 110 and wanted a note. If the developer would fix those issues it would be 5 stars for me.

The app arbitrarily ends the current streak of workouts in the absence of any interruptions in workouts. A bug long overdue for fixing! The app misrepresents the resting heart rate. The difference with the same reported by Apple Health is 9-20. The app periodically fails to sync after the workout. You have to kill the app and restart it. The app always lies about the steps taken. Overall, still a sloppy app!
