### 4/5 — Strava

*2021-05-25*

It’s a legitimate running watch. Work too get with Strava and get privileges to add Strava

### 1/5 — Problems

*2021-03-05*

Worked to start with then it stopped sync and then quit working.   It would not accept any changes to format.   Would not open, then open on its own.   Would not recommend. No support

### 1/5 — Sleep

*2021-02-11*

Can’t you make this at least a bit closer. Most days it says I wake up 1/2 hour after I have been at work. It not even close. This is the second smart watch and the first one was way closer. h-band has it together. The weather was spot on most of the time. I can tell most of this app is made up. Come on I’m sleeping wile having coffee driving to work.Useless. Oh and the last update just changed the icon as far as I can tell. Very frustrating. Dig my old watch out of the drawer.

### 4/5 — App synced up well, but weather doesn’t seem to update.

*2020-07-07*

Aside from the weather not updating, this app works well and paired to watch very easily.  It is almost 10pm and the watch still says the sun is out.
