String

String is messenger which is secure from Invasion of the outside.

your message is very safe through String.

1. String uses End to End RSA-Encryption. it's safe from middle attack like packet sniffing.

2. There is no 3rd party or database server to store your message. The only thing can store your message is your phone and friend's phone.

3. Your should add your friends by tagging friend's phone. We want to protect you from spam or other unnecessary things that bother you. so String uses NFC technology to add friend.

There is no need to make account. just use any name you want.

I'm just private one developer. I hope many people as possible to use this application.
If you have any feedback, just contact me by email or comment. I'll read it and fix it right away.

I have plans to add some feature about private security like lock screen.
