For riders

Get there for a fraction of the fare.

Someone from your campus is probably already driving where you need to go. tag. finds them, shows you exactly what your seat costs, and lets you tag along for your share of the gas plus $1.50.

See the price before you tap

Every trip card shows your current share and what it drops to if the car fills. The full breakdown, gas plus the flat fee, is one tap away. No surge, ever.

Ride with students, not strangers

Every driver verified a college email before posting anything. You see their name, photo, car, and rating before you join.

Your price only goes down

Costs split across everyone in the car. If more riders join after you, your share drops with theirs. It never goes up.

No trip that fits?

Post what you need. tag. keeps looking.

Post a ride request with where you're going and a rough window, like "Friday afternoon." Drivers heading that way see it, and the matching engine checks every new trip against your request until one fits.

When a match lands

  • ✓ You get the driver's profile, route, and time.
  • ✓ You see your exact share before asking.
  • ✓ You ask to join. The driver approves.
  • ✓ You're in the car's message thread.

Paying

Fair by design.

1

Pay in the app

Apple Pay or card, handled by Stripe. tag. never stores your card details.

2

Money moves after the ride

Your payment is held when you join and only released to cover the driver's gas after you both confirm the ride happened.

3

Cancel freely before departure

Plans change. Cancel any time before the trip departs for a full refund.
