If you try to think about any technological thing you can't do on your phone, you probably won't be able to come up with anything. If there's not an application that does something today, somebody will have invented it by tomorrow. Home delivery services, walkie-talkies, virtual bubble popping apps... even tools. Some years ago some works came to my house to install something, they had forgotten their level, luckily enough my mobile phone came to the rescue. You should have seen their face. Therefore, it's stupid to think there's not an app to measure the room temperature of your mobile device, as is the case of this Digital thermometer.
A simple application to measure the air temperature in Celsius or Fahrenheit.
Don't expect any miracles as it's a very simple app for Android that only tells you the outside temperature of your handset. So don't even think about sticking it under your armpit to see if you've got a fever or placing it inside your oven-roasted turkey to check if it's cooked or not. It's more or less reliable, but only in terms of room temperature. Its own developers advise you to leave the device on a table and not touch it for a couple of seconds for a better result.
Simplicity, but loads of adverts
If you decide to try out this simple app, take into account that it's very easy to get a result. The tool shows you the details in both Celsius and Fahrenheit by simply tapping a button and waiting for a few seconds. As a con, get ready for an invasion of adverts and publicity.
