Sonar Ruler vs Secret

Sonar Ruler is a winner in the Best App Ever Awards - "Most innovative use of iPhone hardware" category! The Amazing New Sonar Ruler is an experimental app that uses echoes to measure distances with your iPhone! * It uses the same principles that dolphins use to find food! * It sends a short pulse from the speaker and measures how long that pulse takes to bounce off of something and return to the phone. It then estimates how far away you are. >> Impress your friends with what this unique app can accomplish using only an iphone! << Ϟ GIZMODO.com: "that's a damned neat trick for a phone to be able to do."

Send messages to your friends and colleagues – encrypted so that only they can read the message. Tap and type your message, and with one tap 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.
