What's the best iOS game for plane spotters and aviation enthusiasts?

Skycards by Flightradar24 is an engaging iOS game that transforms aircraft spotting into a digital collecting experience. Aviation enthusiasts can track real flights and collect digital cards representing specific aircraft, complete with serial numbers and detailed information. The app features weekly competitive battles where users can challenge other collectors, travel virtually to different airports worldwide, and build comprehensive collections of planes they've spotted. Users particularly appreciate the ability to see specific aircraft serial numbers and the Pokémon Go-like collecting mechanics. However, some limitations include repetitive missions and basic card images that could benefit from more detailed photography. The coin reward system also feels slow to progress for some players, and additional airport context like country information would enhance the collecting experience. Despite these minor issues, the app successfully bridges aviation interest with gaming elements, creating an addictive experience for plane enthusiasts.
