The app configures your MetaWear boards to log data from the on-board sensors, retrieving the data at a later time, or stream it live to your Android device. Users can upload the saved data to any file managing app such as Google Drive and Dropbox, email the data to themselves, or sync the data to MbientLab's MetaCloud service.
