Garmin provides wearables, sport watches, and hybrids.
The data for the wearables comes from Garmin Connect (Wellness), such as your step summary, detected activities, sleep, etc. from devices such as Vivofit.
The data for the sport watches is available under Garmin Connect (Sports) which has the detailed data to better analyze your activities.
The hybrid devices will have data from both services and we recommend using both for the best data for your analysis.
Garmin has made changes to their API program in the summer of 2016 which provides you with better security and flexibility and as a consequence, some of our features are impacted.
Garmin (and other services) do post processing of the data that they send us. As a consequence of this, sometimes the durations and various metrics will not match exactly because of this.
For Fitbit, Garmin Connect, and a few other sources, we get immediately notified whenever you sync or add a new activity on their end, and thus, the sync button usually does not find anything.
Garmin Connect (Wellness) only starts collecting data from the moment you start using FitnessSyncer. Pro users can request historic syncs, but this only covers the previous 30 days of data.
If you are using Garmin Express via ANT, you can upload all of your history using the FitnessSyncer Uploader.
If this is still happening, you may need to delete tokens from Garmin Connect. To do so:
If you are still experiencing problems, please contact us.
Garmin Connect samples the sleep and can send us a couple updates of the sleep records before it is finalized, but are sometimes indistinguishable between the completed and incomplete sleeps. Depending on when the sync occurs, it is possible that the sleep sent was incomplete. There currently is not a workaround on this.
