Cipher for iMessage lets you send secret and digitally signed messages with Touch ID.

Now you have an easy way of sharing secret information (like passwords, phone numbers, etc). The recipient of your message will be asked to authenticate using Touch ID (or device passcode), thus ensuring that only the device owner will see your message.

You can also use Cipher to digitally sign your message with Touch ID. A digital signature assures the recipient that the message indeed came from you, because you authenticated with Touch ID (or device passcode).

The free version of Cipher enables you to view secret and digitally signed messages you receive. Upgrade to Pro via the in-app purchase to unlock sending secret and signed messages.

I got a twitter link to install this app after I installed iOS 10. After doing so I realized what other reviewers have discovered, that you can't sign nor encrypt iMessages without buying the 'pro' version for 1.99. So I decided to wait and see some reviews of folks who've upgraded to pro. In the meantime, I can't uninstall this app since it's not an app per se. It embeds into iMessage and just says installed on the App Store in your purchased items list. D'oh!

I would have considered paying for the app. Don't lie to your customers.

Quality reviewer

Stuff like this is really a no brainer. Is it worth the negative stars? I actually came to the page, interested in the application. I would have thought about it, but I don't like when developers do stuff like this... that easily made it a no purchase for me. Be honest next time.

Doesn't work unless paid for.


Seriously, how the heck am I supposed to test this app to know if I want to spend money on it, when it's completely unusable without shelling out for the In-App Purchase?

The app loads into iMessage and lets you type, at least, but is an incredibly frustrating bait and switch! What's the point?
