Many times it's been said that the best signal spot is found near a window or past the living room. But did you know that it could actually be in the least expected place? For instance above a table or chair that are far from a window.
Why does this happen? Signal waves don't travel the same way everywhere.

With this app you'll be able to look at the exact numeric value of your mobile phone's signal. A step may imply an important variation on the signal so just move slowly as you look at the signal and you'll see how it changes.

This app is intended for those who have trouble with their devices not having signal or those who need a faster data network (the better the signal the faster it should be).
