Flight Delays app for iPhone and iPad

This app predicts flight delays in advance. Delays are grouped into three categories: "On-time" (<15 minute delay, "Under 1-hour delay", and "Over 1-hour delay."

Key features:

- a simple interface for you to add, update, and manage flights
- a "long term model" that can predict delays several months in advance
- a "short term model" that predicts delays within 24 hours of a flight and can change as new live information streams in; this model has access to more information such as weather and if the previous flight is delayed
- human-readable explanations for the models prediction
- provide feedback on the models predictions
- vector-graphic animations for delay probabilities

The model type is automatically chosen based on how far the departure time is. The two models have been extensively tested. Each was validated by predicting an entire years worth of flights. The "long term model" scored an 81.5% accuracy, and the "short term model" attained a 90.1% accuracy.
