For over 50 years, Let's Go has gathered budget travel advice for the young and the young at heart. Its witty books offer up suggestions on must-see destinations as well as "grit tips", their "locals only" style information that can't be found anywhere else. Bringing their guidebooks into app format allows for new levels of user engagement, such as real time grit tip alerts when passing by a not-to-be-missed destination, trip planning tools, profiles for connecting with other travelers, and the ability to read and write reviews and tips.
