Competition with mobile messengers is not easy. We had to bring life into a simple, clear, and friendly interface. Extra care was needed for the security system, as messaging apps need special data protection.
Tiddle is a messaging app by Tiddleapps that offers unlimited SMS texting and chatting with anyone in the world. It works without advertising and does not take too long to register: once ran for the first time, the app immediately syncs all the contacts via phone number.
We managed to implement all the functionality of the app while maintaining the light, clear look and feel.
