About Hopper: Your Travel Guru in Your Pocket
Planning a trip can be equal parts exciting and overwhelming — countless tabs open, prices that shift by the hour, and no easy way to know if today’s fare is actually a good one. Hopper exists to cut through that. It’s a travel app built around one core feature: predicting where prices are headed before you book.
Plug in a destination and Hopper shows you a price trend, not just a snapshot — telling you whether it expects fares to climb or drop over the coming weeks. Want a flight to somewhere warm? Hopper tells you when to book and when to hold off, so you’re not relying on gut instinct or refreshing a tab fifty times.
Beyond flights, Hopper also surfaces hotel deals, vacation rentals, and rental cars in the same app, so a whole trip can be booked in one place. The interface is simple, and the “Carrot Cash” voucher system rewards both booking through the app and referring friends.
