Hopper's AI predicts whether flight and hotel prices will rise or fall and tells you to buy now or wait, a model it built a 100-million-traveler business on. Free app with paid add-ons like price freezes and flexible cancellation. iOS and Android.
Hopper answers the only travel question that directly costs you money: buy now, or wait? Its prediction models, trained on years of fare data, watch a route and tell you which way the price is likely to move, with a date to act by. The company built a business of more than 100 million travelers on that one trick before most of this category existed, which makes it the elder statesman of travel AI, long before anyone said "AI."
The predictions anchor a full booking app, flights, hotels, rental cars and homes, rated 4.8 on the App Store, though notably lower on Google Play. Around the forecasts sits Hopper's real invention: travel fintech. Price Freeze locks a fare for a fee while you decide. Change or Cancel For Any Reason does what airlines won't. Disruption Assistance rebooks you when the day melts down. Each carries a fee that scales with the fare, the route and how long you want the protection, so weigh it against the ticket price rather than assuming it's pocket change.
Watch a route early, let the app tell you when to strike, and weigh the add-ons like the insurance products they are: worth it on volatile routes and tight plans, skippable on flexible ones. Deal alerts from the watch list are where the famous savings actually come from.
Predictions are probabilities, not promises, and the app sells hard; expect enthusiastic notifications and check final prices against KAYAK.ai before paying. Support at 120-million scale can be slow when things break. And it plans nothing: pair it with a planner like Mindtrip and use Hopper purely as the buying brain.
Still the best answer to "should I book this flight yet." Let it time your purchases and keep your itinerary somewhere else.
