5 stars: Updated review: 5 stars, but still some learning curve. I was able to fix the issue I had syncing steps from Garmin to Google Health by not allowing activities to sync, since steps taken during activities are counted differently. I have to input my activities manually into Google Fit, which is fine, but I did have to poke around a lot for that. However, the help team reached out quickly and that was appreciated.
4 stars: Good app to a point but doesn't do much. It only lete sync one app. And once I got that working it stoped there. If you have more then one app that syncs with the receiving app it screws up the data. So if you just want it for one app then it does the job. But otherwise it's just not enough to be useful.
5 stars: This app is doing an excellent job of syncing all my health data from my Samsung watch to other sources that don't accept data from Samsung such as MFP, FBit, GFit, etc. so it can be extrapolated to things like Echelon to track my full fitness picture. It's non-intrusive on my phone and worth the small fee. Love it. Highly recommend.
5 stars: Recently switched to a Garmin device and needed (well, wanted, I guess) something to sync with Google Fit. Works very well as far as I can tell. Edit: There is something going on with Google Fit as it doesn't show GPS data from multiple 3rd party apps.
5 stars: Awesome app and love the sync mechanism. Giving 1 star less as I am waiting for the historical sync option which the dev is work...
