Who it's for
Two types of student.
One app.
Whether you've got a car and empty seats, or you need a lift — Carma works for both.
Driver
You've got a car.
Fill the empty seats.
You're driving home anyway. Carma finds students heading the same way so you split petrol costs instead of covering them alone.
- Post your route and departure date
- Carma calculates a fair fuel contribution per seat
- Choose up to 3 passengers for a standard hatchback
- The more seats filled, the more fuel cost you recover
- Build a trusted rating from passenger reviews
Passenger
You need a seat.
Get there for less.
Browse rides between your cities, see verified student drivers, and book a seat. Pay only your share of fuel — far cheaper than any train, door-to-door.
- Search rides by route, date, or trip type
- See driver profiles, ratings, and reviews
- Filter by female-only, planned, or last-minute
- Pay only your calculated fuel share + small app fee
- Rate your driver after the journey

Travel options
Rides that fit
student life.
Not every journey is the same. Carma offers flexible trip types built for how students actually travel.
Female-only
Female-only rides
Female drivers can offer seats exclusively to female passengers, creating a safer and more comfortable environment for those who prefer it.
Planned trip
Planned journeys
Know when you're travelling? Post your trip ahead of time so passengers can book early and plan around it — end of term, specific weekends, whatever works.
Last minute
Last-minute seats
Leaving today or tomorrow? Post a last-minute ride and passengers on the same route get an instant notification to grab a seat.
Trust & community
Verified, rated,
and reviewed.
Every person on Carma is a confirmed student. Every journey builds a reputation. Trust is earned, not assumed.
University email only
Sign up with your .ac.uk or institutional email. Only verified students can create an account — no exceptions, no workarounds.
Profile with photo & bio
Every user uploads a profile photo and writes a short bio with their year and degree. You always know who you're riding with before you agree to anything.
Ratings after every ride
Passengers rate drivers and drivers rate passengers after every journey. Public ratings build community reputation and reward good behaviour on both sides.
