Fare alerts
● not set up
Watched routes are checked every night. When a fare drops, you get a push notification.
Preferences
Home airport prefills From. Saved on this device only. (Mac alerts already stay quiet overnight, 10pm–8am.)
Search budget

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.
