This page shows statics across all submissions in our database, either as a device statistic (the average of each device occurs once regardless of how many users submitted data for it) or as a user statistic (each user occurs ones).
Note, that this includes thermometers that are not designed to measure ambient temperature. In fact, most thermometers in smartphones tend to be rather unreliable as they are more subject to the internal heat of the device than to ambient temperature.
