DarkSpeed: Bike Speedometer
GPS Cycling Computer & Cadence
Only for iPhone
Free
iPhone
One big number, full screen. Auto-start, plus live cadence and ultra-accurate BLE wheel speed. No account, no cloud — your data stays on your phone.
DarkSpeed is a GPS bike speedometer (and more) built for one thing: so you can read your speed at a glance from your handlebar mount. No maps, no account, no clutter. Hop on your bike and the app starts measuring on its own.
In short: one big number, full screen, OLED friendly and zero distractions!
SMART AUTO-START & AUTO-PAUSE
Forget pressing "start" with gloves on. DarkSpeed uses a two-layer motion filter (GPS + accelerometer) that eliminates false triggers:
• Auto-start once you pass the speed threshold
• Auto-pause after 10 seconds of standing still
• No accidental starts when a bus drives past
ACCURATE GPS SPEED MEASUREMENT
• A Kalman filter smooths the reading — speed won't jump around like on basic GPS apps
• GPS + accelerometer fusion: two independent layers confirming motion
• km/h offset calibration — match the reading to your car's speedometer
• km/h or mph units
BLE SENSORS: CADENCE & WHEEL SPEED
• If you like, pair a Bluetooth speed & cadence sensor (CSC standard)
• Speed measured from wheel revolutions — ultra-accurate and independent of GPS signal quality (forest, tunnel, dense city)
• Live cadence straight from the crank
• Adjustable wheel circumference
LIVE STATS & RIDE HISTORY
• Current, max and average speed, distance, ride time
• Full ride history saved locally on your phone
• Per-ride stats: distance, time, max and average speed, date
• Persistent lock-screen notification: average · distance · time — without unlocking your phone
DESIGNED FOR OLED SCREENS
• Black background = real battery savings on OLED screens
• Burn-in protection (subtle pixel shift)
• Ride mode with screen dimming
• Screen stays on while riding (wake lock)
PRIVACY WITHOUT COMPROMISE
• No account, no sign-up, no cloud
• Your routes and stats never leave your device
• We never sell your data
SPEAKS YOUR LANGUAGE
50 European languages — English included, of course. The app automatically matches your phone's language.
WHO IS IT FOR?
DarkSpeed is a bike computer in your phone — for anyone who just wants to see speed and distance: commutes, weekend rides, road and gravel training, amateur cycling. If you don't need maps or a social feed but want a clear GPS speedometer — this is the app for you.
Start free with GPS-based speed. And when you want measurements like a classic bike computer, add a BLE sensor (around ~10 EUR) and get turbo-accurate readings straight from the wheel.
Download DarkSpeed and turn your phone into a bike computer that just works.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• When you pause a ride, the speedometer now correctly drops to zero instead of showing live speed.
• The main speed readout is steadier — the big number no longer briefly shrinks.
