DelayProof

DelayProof is a mobile + web AI app that predicts public transit delays and crowding 10–30 minutes ahead, then recommends the least-bad alternative (different line, different stop, walk-to-transfer, bike share, or rideshare only when it truly saves time). It combines official GTFS-realtime feeds with anonymous, opt-in phone sensor signals (motion + GPS) and user “I’m stuck” reports to detect breakdowns faster than agency alerts. The app focuses on commuters who care about reliability, not pretty maps: it sends proactive push notifications when your usual route is trending toward failure, and it offers a “leave now / leave later” decision with confidence scores. Brutal truth: you won’t beat Google Maps on general routing, so you don’t try—you win by being earlier and more honest about uncertainty and crowding.
