This app is very frustrating. Scans constantly fail. App will invalidate sensor after too many failed scans on a row. App trashed a sensor after 7 days. Awful account controls and no data transfer to new phones. While trying to set up a new phone I logged in to my account. This logs you out of the old phone, but NO DATA TRANSFERS. You lose months of valuable data. There is no way to log back on to the old device either. App nerfed my text notifications too App needs a serious overhaul.
