First up, both me and my wife have this app. For just me, I’d give it 3 stars. My wife, however, is sometimes not receiving notifications so I’m knocking off a star. Also, I like the watch itself, this rating is purely for the app. So, what it does it does pretty well, but as it stands, it’s missing some key features. The key ones for me as as follows, -Should allow for continuing vibrations for calls and alarms. -Should allow for the phone alarm and reminders to send notifications to the watch. -Needs more app support. The key one missing for me is the Outlook app. As it stands, I can’t get vibrations for work emails, which is annoying. Really, it should be able to access any app that gives notifications (but I only want it to work for Outlook). Fix those issues, and it would be a 4* app. Some nice-to-haves to get it up to a 5* app would be: -Sleep tracking -Being able to set different vibrate lengths or patterns -There’s a red LED in the watch. Red should be one of the colours availabe. -The ability to add more than 5 contacts to ‘My People” I don’t use the curiosity feature. The step tracking seems accurate enough but I haven’t checked it’s accuracy. I understand that it doesn’t pick up short walks, which I can understand would be annoying for some people. It’s still a relatively new app, and most of the things I want it to do seem like they could be added fairly easily. If they are, I’ll update the review.
