Threema is a new mobile messaging app for Windows Phone that is billed as putting privacy first with end-to-end encryption to help insure that your messages can only be read by you and its intended recipient.
We had heard rumblings that the messaging app was in the works for Windows Phone over the summer and it hit Store shelves this morning. Threema's claim to fame is the security it offers through not only its encryption but also the anonymity. You can use Threema without the need for personal information such as email addresses or phone numbers and your messages are deleted from Threema servers after delivery.
At first glance, Threema comes across as an appealing and feature rich messaging option worth considering.
