Great idea

Really good idea, execution poor. The current version requires the recipient to open a message twice in order to see it.

I call BS

Optimized for iPhone X? Are you kidding? The apo is terrible and I wonder what they mean by military grade encryption lol.

140,000 people are using it... In what parallel universe?

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.
