From Digital Bananas:
Using a special algorithm based on your touch we can analyze and identify your feelings. Touch and rub the sensor with someone else and find out what someone else thinks and feels about you by the way they touch.Upgrade and use an alternative sensor that will measure your sex appeal through the way you touch. This app uses a sophisticated algorithm to determine a person's feelings by their touch and movement and other factors. However, this algorithm is not always accurate therefore it should only be used for entertainment purposes.
