Blunt: Rate Everything

Blunt measures public sentiment on everything. Search anything (a restaurant, a product, a city, a song, an idea) and get its Blunt Score, a number from 0 to 100. Our algorithm reads the most relevant sources across the web and measures their sentiment. Users add their own ratings and reviews to affect the topic's Blunt Score.

Blunt is live on iOS, Android, and the web, used by 100k+ people across 145 countries.
