UniPool

Every homecoming season the hostel WhatsApp groups fill up with "anyone sharing a cab to the airport?" — and every useful message gets buried. UniPool replaces that with a real app: search rides by date, time, and budget, or host your own, set a price per seat and a seat count, and accept or reject requests to join. There's an explore view for slots around your preferred time, too.

Live on both the Play Store and the App Store.
