Best way of communication with the people in your life in full privacy.
En1gma Messenger is simple way of texting and you dont have to pay for every message (it works with your data plan).
It allows you to access and read your messages only after verification of your fingerprint(It will only work with the cell phone device that has the fingerprint feature), so if anyone else will try to access you text messages they will not even be able to see the person or content of received or sent messages since it will be all encrypted.
It allows you to keep all the important messages and not to worry about anyone else accessing it with or without your permission.
