Tatome tells you the person who calls you if you can't look at your phone. A good example is you get a call when you are running with a sporttracker and music with earphones. You have to look at your phone to see who is calling you. Tatome tells you the caller without looking at your phone so you know who is calling you.
Tatome is only activated when headphones are plugged in by default. The volume of the ringtone can be changed.
Tatome is free without any advertising. But you can buy a premium in app product which enables some more options like:
Use the text to speech without a attached headphone. Modify the spoken text by yourself.
