I work nights and I’m not always in a position to sync before midnight. Unless I do, none of the data between my last sync and midnight gets loaded and has to be manually input.
I bought the full version specifically because syncing in the background was listed in the settings but not available on the lite version. Come to find out, it’s also not available in the paid version, either, but will be included in a future upgrade.
If I’m going to have to manually enter Fitbit data into Health, I don’t need this app. So, meh.
