Cryptobot is a mobile messaging app that puts security and privacy first. With true password protected encryption, you can rest assured that only you and the intended recipient can read your messages. All messages are encrypted, private and 100% yours. All encryption happens on your device, and asymmetric cryptography ensures that only the intended receiver can read your messages. Encrypt and secure your messages with password and one of the most secured encryption algorithm. Email, SMS, Tweet or post on Facebook secret messages between friends using this simple application that encrypts a given text with passcode, and just as easily decrypts a given text with the same key. Cryptobot is a zero-knowledge messaging app. This means we cannot read, decrypt or share your messages. Like Cryptobot on Facebook: http://goo.gl/gvnBrO

Verdict
The clearest difference is ads: Cryptobot at none against iSecure's shown. Cryptobot also leads on iOS requirement (11.0 vs 17.0). iSecure's advantage is update cadence (every 2 days vs every 32 months). On price, in-app purchases and device support there is nothing between them.
