Pretty Good Privacy (pun intended)
It encrypts really well. A good app. One of the great feature about this app which is not mentioned anywhere is that it also serves as a secondary check for people like me who sometimes sends messages to the wrong party because of the tendency to tap the "Send" button before checking who the recipient is.
However the black bubble currently works only for SMS and iMessage. In order to use this app for other texting app like Whatsapp, only the link works. And so when using the link, there is a manual process of pressing the green unlock button in order to decrypt (unlike the black bubble which black SMS decrypts automatically).
Thanks for developing this great app!
What would be a really good improvement for this app is to actually have texting capabilities. This would solve the "switching-between-apps" inconvenience that some face.
