Hopper is a travel booking app founded in 2007 and based in Montreal.
Hopper studies price history and tells users whether to book a flight now or wait for the price to drop. Users can watch a trip and get a push alert when the price changes. Hotels, homes and car rentals can be booked in the same app. Paid add-ons let travellers freeze a price for a few days or change and cancel trips more freely.
The app is free to use. Hopper earns money from bookings and its optional travel protections.
