okay, the state of pebble time fitness tracking is really sad and this one seemed super promising.
two nights using sleep tracking, apparently you need to leave bluetooth on to actually track it. no perpetual storage use there, not even to like purge it once it syncs to the phone the following morning.
step counter, stand alert work fine. the regular timer needs a little work (i prefer H:M:S format), i didn't test powernap or smart alarm yet. unsure if this utilizes the wakeup API either.
but i managed to lose 60% of my pebble time's battery in under 24 hours using this!
this only seems to connect to healthkit via runkeeper which, despite the setting being there, doesn't handle your sleep data so it's just stuck on the letsmuv app.
and sorry for being the american weirdo that uses the imperial system to measure myself, but i've had to overestimate my height and weight because of this oversight.

this COULD be super good, but looking on your posts in the pebble forums and zero tweets since march puts off a lack of interest in continuing this. so whatever, i'll just runkeep my daily bike rides and nothing else i guess.

Not Amused-- worst app

Don't waste your time with this app. All I really want was a simple app that could accurately track my sleep. Not only did that not work (it was showing there was no data after the first night, even though I clicked the start sleep button before I went to sleep), but it drained the battery on my phone and watch since it was perpetually syncing data. Every time I woke up I couldn't see what time it was on my watch due to the message that it was syncing Lets Muv, and I couldn't get that message to leave the screen. Even at 8am, it was still syncing data. The only way I could get it to stop was by deleting the companion app and then unloading the app from my watch. So frustrating!

Great Idea, Ill Conceived

I recently received a pebble time, and letsmuv appeared to be the most comprehensive fitness app available.

While it does have a lot of features, it is lacking explanation of how to set them up or use them. I have yet to figure out the purpose of, or how to utilize sleep mode, and havent been able to get the stand alert to work.

The most frustrating thing is that my steps/muvs/calories/distance has not reset for a new day on the pebble, it's just adding to my previous total. It's refreshed on the web site to start again at 0, but not on the watch.

There is also not continuity of icons. There are different icons on the watch as there are on the app/web site that mean the same thing, but again, not a lot of explanation as to what they represent.

For now I will be switching to Misfit, but hope to return to Letsmuv after improvements.
