About this app
Ever wondered how much time you actually save by driving faster? The answer might surprise you.
Don't Speed Up is a GPS speedometer that flips the script: instead of showing your speed in km/h or mph, it shows how many minutes it takes to drive a fixed distance at your current speed. This simple reframe makes the diminishing returns of speeding impossible to ignore.
At 60 km/h, it takes 50 minutes to cover 50 km.
At 90 km/h, it takes 33 minutes — you save 17 minutes.
At 120 km/h, it takes 25 minutes — going another 30 km/h faster only saves 8 more minutes.
The faster you go, the less each extra km/h matters. That's the math of speed, and this app makes it visceral.
FEATURES
Analogue Gauge
A beautiful 270-degree circular speedometer with two scales: the outer ring shows your conventional speed, while the inner ring shows minutes per distance. Watch the needle move and see both perspectives at once.
Digital Readout (Premium)
A clean, oversized numeric display designed for at-a-glance reading. Responsive layout adapts to portrait and landscape orientation.
Fuel Penalty Display (Premium)
See in real time how much extra fuel you burn by exceeding your economy speed. Based on simplified aerodynamic drag physics — the faster you go, the more fuel you waste.
Show Me The Math
An educational screen that walks through the formulas: why time savings diminish, how aerodynamic drag scales with speed squared, and how different vehicle profiles affect fuel consumption.
Smart GPS Filtering
Weighted moving average smoothing, accuracy filtering, and consecutive-reading requirements ensure the display is stable and trustworthy — no jittery numbers from indoor GPS drift.
Motion Lock
For safety, the app locks navigation while you're moving. A passenger can disable this in settings.
Multilingual
Available in English, Polish, and Italian.
Units
Automatically detects your locale and shows km/h or mph. Switch anytime in settings. Distance reference adapts accordingly (50 km or 30 miles).
Don't Speed Up doesn't tell you to slow down. It just shows you the math — and lets you decide.
