I have a fitbit (a clip one) but it has stopped syncing with my phone numerous times. I have uninstalled and installed the app and it works again for a bit before stopping again. At the moment I might as well be wearing a cheap pedometer. I love the Bellabeat Leaf but having read some reviews I see that people have problems syncing that too. Any ideas? I don't mind if it is a wrist one or a clip one as long as it syncs. My phone is a Samsung s5 if that makes any difference. Thanks!
