Send messages to your friends and colleagues – encrypted so that only they can read the message. Tap and type your message, and with one click you can encrypt and then send your message, or copy it to the clipboard for pasting in to another application. Shake to clear your message.

Secret – just between you and me...

When someone who has Secret installed receives a Secret-encrypted message, they need only click on the message and they are taken straight to Secret where they can decrypt the message with a pre-arranged password. It's as simple as that!

Secret uses DES symmetric encryption to keep your messages safe. You can use it anywhere you need to send a message that you don't want others to read. The decrypted message is not stored on your phone, so if someone intercepts or finds your phone, they can't read your messages without knowing the password.

Secret works in any language, and even with emoji. Secret is also fully localised in English, French, Japanese, Italian, Greek, Spanish, Malay, Indonesian, German, Korean, and Simplified and Traditional Chinese.

Secret – it's the easiest way to secure the messages you send and receive.

Is working on iPhone 4

I have an iPhone 4, my friends who run this have iPhone 4s, and I developed it and tested it on an iPhone 4. Perhaps Night hawk4000 is not putting the correct password? Have you tried turning your phone on and off in case there is something wrong with the OS and it needs a reboot?

Very Useful App

It is great to know that even if I leave my phone lying around no one can peek at my most important messages. Works as advertised and the graphics are great too.
