Tried free version and only part of syncs works. The one that works have 1/2 -1 day delay. Probably good enough value for free version but can't think about buying it.And even for 100% bug-free unlimited version the price extremely high.
Developer Response
I'd love to understand more of your setup. In general, integrations all work, but may take time to complete or have particularities with your data. But we do offer a ton in the free version, and no integrations should work differently in the free vs Pro version outside of the features like Historic Sync. Feel free to contact us at hi@fitnesssyncer.com at any time to discuss more.
App is improving with each itteration.

Great little utility. I use for syncing my sleep with trainingpeaks. The app was initially quite clunky and prone to crashed. However the developer has been addressing these issues and things are working great now.
Developer Response
Thanks for the feedback. Sync-on-Demand is available by swiping the items on the Sources and Destination screen. Our Beta version has resolved a bunch of crashes; if you are still experiencing some, please report them so that we can resolve them: support@fitnesssyncer.com. Thanks and have a great day.
Expensive and not very functional
chad!!!!!!
The interface is clunky and unpolished; and at this point the weight, sleep states are either not pulling from Garmin or not pushing to TrainingPeaks, it’s hard to see where the fail point is.On top of that, the pro sub is petty pricey for what this is.
Developer Response
Sorry to hear that! We are always improving the app.As for issues with troubleshooting your issue, you can always reach out to us at support@fitnesssyncer.com -- the FitnessSyncer Stream is a great place to look at what is coming from Garmin and our FAQs cover some limitations of TrainingPeaks, but we can also guide you through that.We have a very generous free tier that you can do a lot with -- but we are also always adding value to your FitnessSyncer Pro subscriptions.
