This app is intended for entertainment purposes only and does not provide true Thermometer functionality.

Thanks to the built-in barometer of your iPhone 6 / 6S / 6+ / 6S+ this app calculates an approximate temperature based on the law of Boyle. After a one-time calibrating your iPhone can calculate your current sourounding temperature. But still, a classic thermometer will be always more accurate than the App.

It is therefore important to note that the temperature measurement is carried out exclusively in closed rooms. Open doors and windows may reduce the accuracy significantly!

Have fun with the app!

This app does not work at all! it asks you to enter the temperature to calibrate it but how are you meant to do that when the reason for the app is to find out the temperature!? Such crap.

I want my money back!

Doesn't even work! Don't waste your money paying for it.

Miserable false advertising!!!!

I'm in the USA and there is no conversion from Celsius. The app cannot give temp - it needs to have it put in. Refund the money!!!
