THE STORY BEHIND TONELENS
Built in 7 days. I just kept going until it worked.
THE PROBLEM
/*
* People miss 70% of what's really being said.
* A nervous laugh. A confident tone hiding desperation.
* Crossed arms. Avoiding eye contact.
*
* Google Translate gives you words.
* ToneLens gives you truth.
