4 stars: Mostly good. I purchased the one time / lifetime subscription. Everything works good, except sometimes it doesn't sync my sleep data properly. This is syncing from a Galaxy watch 4 classic / Samsung health to Google fit, on a Samsung S20 FE phone. It does get my fitness / step info correct. I do like the historical sync when you buy the full version.
5 stars: I don't usually rate high or pay for apps. But after a year using this, and the updates that has been done, this is really a great product to move data around. I want to see all my data in Google Fit. I have a Samsung Gear S3 smartwatch and a Fitbit scale (used to have Fitbit watch too). This works seemlessly with all three. Great product. Money will spent.
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: Its reliable. It does what you want it to do, which is to sync your activity from your fitness tracker to your most popular fitness apps. If you do experience syncing issues, Health Sync will let you know and it is most reliably based on Permission Setting in the apps. Turn them on and you are good to go.
3 stars: Sadly, this does not work in the USA when syncing with the Huawei health app. Not really an issue with this utili...
