Enigma is a minimalist, locked-down one-to-one chat app whose main focus is to secure the chats. Individual chats can be hidden/locked and can only accessed via either Fingerprint Authentication, if it is available, or through plain old passcodes.
Enigma doesn't have forwarding enabled, so no fake news. It also doesn't send out pesky notifications so you can chat when you feel like it. One of the good features of Enigma is how easily it lets you delete an entire conversation. A right swipe on your friend's message will delete all the conversation up until that message.
And all this is available in under 10 MB.
