Hopper
Hopper is a travel app that predicts prices, tracks deals, and lets users book flights, hotels, homes, and rental cars.

Hopper helps travelers search and book flights, hotels, homes, and rental cars. Its price-prediction tools analyze travel prices and notify users when to buy, while AI Mode can find deals, track trips, and suggest destinations.
The app also offers optional products such as Price Freeze, Cancel for Any Reason, Change for Any Reason, Leave for Any Reason, and Flight Disruption. The mobile app is free to download, but bookings and optional travel products may cost money. Some features are available only in the app.
