Free version only allows 5 sources or destinations of data combined. It has potential with the ability to better sync all of your data and present it in graphs you'd want. App to website seems a great idea to see charting on a bigger screen. This has potential. I WOULD purchase an app like this for a one-time fee, but monthly or yearly subscriptions are not worth it to me. The free version would likely work if you were trying to get data from a Fitbit into one repository only. I use Samsung Health and GoogleFit, run several fitness apps and have them all feed into either / both of these. The concept is there, but the execution, limitations in a free version, and subscription model made me uninstall.

Thank you for the feedback! We understand that some complex use-cases do require more than 5 sources and destinations, but you can do a lot with our free service.

I own a popular flagship OnePlus 7 Pro and the app won't even open. After installation TRYING to register for an account it completely locked up the phone. I forced a device restart and tried to open the app. The opening screen showed up with the options to create account, login, etc. I tried both create and login, in case the account was created the first time, and it did nothing. A great idea for an app, unfortunately, the execution is an epic fail.

Sorry to hear about your experience -- please update to the beta and contact us at support@fitnesssyncer.com so that we can assist you and get to the bottom of this -- we unfortunately have not reproduced these and are trying to help! 1 star reviews don't help developers resolve issues they cannot reproduce.

App was barely functional before the last update. I had to go through Intervals.icu to get actual correct activity data from Huawei, because directly it would get data all wrong. Health Connect never worked for me, but Samsung Health did and was ok. Now, after the last update, every time I try to use either Health Connect or Samsung Health the app just crashes. I tried contacting support, like they ask you to in every reply here, but they are useless. Just use the competitor Health Sync instead.

So sorry to hear about your experience. Huawei is still in beta due to inconsistencies in their documentation and unclear your Google Health issue, but guessing its the message for a Google Health Connect update. We help where we can and happy to keep helping: hi@fitnesssyncer.com .
