Fitbit continuously follows the motto of one step forward, two steps back. Their trackers continuously loose useful functions. The app has been okay. Doesn't allow you to export years of data as I've made the switch to Garmin. Fitbit continues to push their premium service, holding YOUR data from you behind s subscription wall. After the charge 5 lost it's altimeter and no plans were made to add it back I realized they simply don't listen to their customers. Garmin is far more superior.
