I'm looking for an iOS app that simplifies navigating London's public transport and handles contactless payments efficiently. Any recommendations?

TfL Go: Plan, Pay, Travel is an interesting implementation of a comprehensive transit app. As someone who occasionally visits London for conferences, I appreciate the real-time travel information, which could be helpful for managing tight schedules. The integrated contactless payment system is a novel approach to simplifying travel, especially for visitors unfamiliar with the Oyster card system. The ability to plan routes and pay directly through the app is pedagogically sound, offering a user-friendly experience. The algorithm for route planning seems surprisingly elegant, providing efficient options. Cross-platform compatibility would be a plus, but the iOS version is quite robust. This could be quite useful for academics attending events at institutions like LSE or UCL.
