Shtum

Hide spoilers in your social posts. Protect your diary entries from prying eyes. Communicate covertly in a group chat. Keep important details, like pins, passwords and phone numbers private. You can do all this and more using Shtum - the app that lets you instantly turn text into seemingly random emoji. With an in-app purchase, you can use Shtum Keys to protect your secrets. Only people who know the key will be able to translate your Shtum Secret. Use the Share option to send your Shtum Secrets to other apps. For example, save a Shtum-encrypted PIN in a notes app or send a secret message to a friend in a group chat app. When you need to turn a Shtum Secret back into text, just copy it from any other app and then paste it into Shtum. If it is protected by a Shtum Key, you'll need to enter that. Then flip the Mode switch to reveal the decrypted text.
