Really good idea, execution poor. The current version requires the recipient to open a message twice in order to see it.
Nice idea, but falls short
The receiver of the messages has to know what password was used to encrypt each of your messages (if you don't know their password, you can't read their messages). Assuming you're texting this person, there's a good chance that password will be sent in a text, making it available for anyone who really wants to read your messages.
You have to individually copy and paste (which is impossible to tell when the message has been pasted into the app, no paste button) each time your want to send or receive an encrypted message. There are several other apps out there that offer an alternative to using an standard SMS or MMS that don't require constant copy and paste (many of them are free!). It would be much simpler to send the messages over the internet directly through the app so that you are not jumping between apps all the time.
Pretty good but A couple recommendations ..
The app works well and the black bubble and lemon texting are great ideas. A few issues however:
It's great that when you leave the app (even without closing it) your displayed decrypted message/pic disappears. The only way for someone to bring it back is to repaste and input pw. HOWEVER if you don't use the page turn icon or close the photo or app then your secret photo stays displaying in the app. i.e. you're viewing private photo and someone walks up quickly so you quickly hit home button. The app is still open in the background so if you forget to go back and close that pic then someone can pickup your phone and open that app and your pic will still be displayed without re-entering a pw. Please fix this.
Also you can use 'link' method where you can just press the link in regular iMessage and hit 'open'. That opens the program automatically and gives you a pw prompt. Very few steps. However if you attach a photo it converts automatically to black bubble method.
If these things were fixed (mainly the photo staying issue) then it would be a 5 star app.
With Family Sharing set up, up to six family members can use this app.
