grimmdaniel/cheap_price_detector — reverse-engineered prompt

Build me an iPhone app for finding cheap flight tickets when the exact travel dates don’t matter. I want users to pick a departure airport and destination airport, either from a list or an interactive map, choose the minimum and maximum number of nights, then choose the first and last day of the date range they want searched.

The app should quickly scan lots of possible date combinations, show the cheapest options first, and let the user sort the results in other useful ways too. Include an option to show discount club prices when that applies. When the user picks a flight, the buy button should open the airline’s official website to finish booking.

Also add a “My Flights” area where users can manually save flights they’ve taken or plan to take, with origin, destination, dates, and other basic details. They should be able to see saved flights in a list and on a map.

Make the UI simple and polished, like a real travel app. Use Swift for iOS, and look up current Apple docs online if needed.
