Ive had my Nabu since September 2015 but I avoid syncing my Nabu since it will always reset my display settings and lags horribly when attempting to swipe between days - dont even get me started on trying to sync more than one day. Its pretty much a nice watch/fitness tracker but I dont bother trying to sync my data to use the graphs since the app is so poorly made. Having to log in every time is annoying too. Edit 5/12/2016: Newest update immediately crashes upon opening and syncing for a few seconds, making it even less usable than before :( I just want to change my Nabu settings
