If you want to find out how strong your cellphone signal is, the information is at your finger tips with an app and a map. OpenSignalMaps uses Android smartphones to gain information so that they can crowdsource locations of cellular towers and measure their strength.
The concept was developed by Staircase 3, who would like to create accurate signal maps with its Android app and OpenSignalMaps website. The OpenSignalMaps app has been doing extremely well with over 80,000 downloads so far.
