Watched routes are checked every night. When a fare drops, you get a push notification.

FareScope stays free by capping live searches. Cached results and re-sorts never spend anything.
How this works
Prices are live Google Flights prices, fetched the moment you search. Tap through to Google Flights and book directly with the airline — FareScope never books and never takes payment.
If a search would blow the free budget, FareScope tells you instead of showing stale numbers. No made-up fares, ever.
On iPhone
Add FareScope to your Home Screen (Share → Add to Home Screen) for the full-screen app and push fare alerts.
