GPS Speedometer

Speed shown
in minutes,
not km/h

A different kind of speedometer. See how many minutes it takes to drive a fixed distance at your current speed — and why pushing harder barely saves any time.

The faster you go,
the less time
each km/h buys you

The gauge shows minutes to travel 50 km at your current speed. It's simple division — but the result is eye-opening.

Going from 60 to 80 km/h saves 12 minutes. Going from 100 to 120? Only 5. The returns diminish sharply because time is the inverse of speed — a hyperbola, not a line.

Once you see your speed in minutes, you start asking: is this extra fuel and risk really worth 2 minutes?

speed time / 50 km saved vs prev
60 km/h 50 min
80 km/h 38 min -12 min
100 km/h 30 min -8 min
120 km/h 25 min -5 min
140 km/h 21 min -4 min
160 km/h 19 min -2 min
time = distance / speed — the curve flattens fast

Built for the drive

Analogue gauge

A 270-degree speedometer with dual scales — km/h on the outside, minutes on the inside. Reads at a glance.

Digital readout

Large numeric display that adapts to portrait and landscape. Designed to be readable from a phone mount.

Fuel penalty

Shows the extra fuel cost of going above your economy speed. Based on real aerodynamic drag physics.

Math screen

An in-app explainer breaks down the physics — diminishing time returns, aerodynamic drag, vehicle profiles.

Smart GPS

Smoothed readings with EMA filtering. Requires consistent signal quality before displaying speed — no jittery numbers.

Motion lock

Locks the interface while driving so you stay focused on the road. Safety first — the gauge does the talking.

Speed costs more
than just time

Aerodynamic drag grows with the square of speed. At highway speeds, it dominates fuel consumption. The app calculates a fuel penalty based on your vehicle profile and economy speed.

A sedan at 120 km/h burns 28% more fuel than at 80. An SUV? 38%. These aren't guesses — they're physics.

Sedan at economy speed 80 km/h
100 km/h +12% fuel
120 km/h +28% fuel
140 km/h +47% fuel
160 km/h +66% fuel
Drag weight by vehicle profile
profile penalty at 120
Sports car +19%
Sedan +28%
SUV / Van +38%
01

Free forever

The core app is fully functional at no cost. No paywalls blocking the gauge, no premium upsells on safety. A small unlock exists for extras like the digital readout and vehicle profiles.

02

No ads. No tracking.

Zero analytics. Zero ad networks. Your location data stays on your device. The app doesn't phone home, ever. Because a speedometer has no business knowing who you are.

03

Drive aware

This isn't about going slow. It's about knowing what you're trading for speed — time, fuel, safety. Once you see it in minutes, you make better decisions. That's the whole point.
