Adventure Guard is an app designed to keep travellers safe. It warns you when you’re wandering into an area where many crimes have been reported. It also alerts users to popular scams uncovered around their destination. Catarina Birch helped to build the app after a scammer in China detained her and ripped her off. She’ll warn you about the ‘Tea Ceremony’ scam, which prompted her to do something in the first place. Find out more at AdventureGuard.net.
