Handy, quick and accurate : the best thermometer for your iPhone / iPad
The n°1 thermometer in the App Store, with over 5,000,000 downloads!
@Thermometer is the most accurate application in the App Store (down to a tenth of a degree).
Since 2009, @Thermometer is the ONLY application to give you the outside temperature to the nearest tenth of a degree, in line with your exact location, throughout the world and in real time.
To achieve this, @Thermometer uses multiple data sources from your surrounding environment and combines them together thanks to our own unique algorithms developed on our meteorological servers.
@Thermometer is NOT just another application that tells you the temperature in a nearby town, using hour-old – or even older - data...

These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
