Smart commuter carpool · MVP prototype

Share the route you already drive.

Der Pendler matches commuters whose recurring routes and time windows overlap — so daily driving costs go down, traffic eases, and no one has to plan a thing. Not a taxi. Not Uber. Just everyday commuting, shared.

How it works

1

Set your recurring route

Tell the app where you commute from and to, your departure window, and any flexibility on pickup or drop-off zones.

2

Get matched automatically

The route-intersection engine compares your geography and time window against other commuters — no AI, no guesswork.

3

Confirm, drive, split costs

Passenger requests, driver approves, PIN handshake at pickup. Payment is settled automatically when both confirm completion.

Built for everyday commuting

🔐 Auth & biometrics

Email, Google, Apple login with optional Face ID / fingerprint unlock for trusted devices.

🚗 Dual roles

Be a driver, a passenger, or both — switch at any time with one tap.

🗺️ Route intersection

Lightweight geometric matching of polylines + time windows. Predictable, debuggable, fast.

📋 Ride dashboard

Counters for available rides, pending requests, and upcoming commutes — everything one tap away.

🔢 PIN handshake

Both users exchange a 4-digit code at pickup to confirm identity and activate the ride.

💶 Fair split

Passenger covers ~⅔ of fuel cost. Platform keeps a flat €0.10 per ride.

Safety, by design

Carpooling lives or dies on trust. Der Pendler adds two layers that don't get in the way of daily use: verified identity on signup, and a PIN handshake at every single pickup. If the codes don't match, the ride doesn't start.
