I kept obsessively checking Google Flights hoping prices would drop. So I built Descent, set a budget for any route, and get alerted the moment fares go below it. It tracks business/economy class, direct flights, multiple currencies, and passenger count. The fun part: Descent Copilot lets you create alerts by just saying “Cheap flights to Tokyo in August under 150 euros”, powered by Apple Intelligence, fully on-device. Free to try. Would love your feedback!
