This works for the use case where the user never uses the companion app, which in turn means never using things like alarms, and so on. Any operation connecting the app to the phone requires syncing first, which takes an inordinate amoujnt of time (I don't have the Bip anymore, but I think it was a minute or so). On top of that, if the app has been recently updated, the AGPS will need to be resynced, which AFAIR, takes a few minutes. Zepp sucks in this department. Modern Amazfit smartwatches still take a disproportionate time (compared to the competitors) to sync, but at least they do it asynchronously.
