DarkSpeed vs BikeSpeed

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, so speed won't jump around like on basic GPS apps • GPS + accelerometer fusion: two independent layers confirming motion • mph offset calibration: match the reading to your car's speedometer • mph or km/h 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) PRO The Pro module gives you complete control over your cycling fitness with clear progress charts, a colorful activity calendar and cadence alerts that help you maintain the ideal rhythm. Keep your momentum going and protect your bike by tracking personal records, monitoring riding streaks and receiving maintenance reminders based on your accumulated mileage. You also gain access to exclusive ride screen themes, secure file export and restore for your entire route history, and all future updates included at no extra cost. 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 (about $10) and get turbo-accurate readings straight from the wheel. Download DarkSpeed and turn your phone into a bike computer that just works.

BikeSpeed is a simple GPS speedometer made for cyclists. Unlike many other speedometer apps, BikeSpeed is completely free. No ads, and no subscription required. Mount your phone on the handlebar, tap Start, and start riding. WHILE YOU RIDE • Large, easy-to-read analog speedometer • Live trip stats: average speed, max speed, distance, duration, altitude, climb, descent and gradient • Direction of travel with a compass arrow and the name of the street you're on • Automatic pause • Your trip keeps recording even if the screen locks or you switch apps, so you can put the phone in your pocket along the way • GPS signal indicator. When the signal is too poor to trust, speed and distance freeze to avoid false readings • The screen stays awake while you ride TRIP LOG • Every finished ride is saved with date, distance, duration, average and max speed, and total climb and descent • Your route drawn on a map — tap the map to explore it full-screen with pan and zoom • Height profile and speed profile • Totals across all your rides and personal bests: longest ride, best average speed, top speed and biggest climb • Export a ride as a GPX file to Strava, Komoot or other apps ICLOUD SYNC Your trip log syncs automatically to your own private iCloud, so rides, routes and records follow you across your own iPhones. Not signed into iCloud? Then everything stays on the device. SETTINGS Set your own max speed on the gauge, switch between metric (km/h) and imperial (mph), turn automatic pause on or off, and choose Norwegian or English independently of your phone's language. PRIVACY You don't have to sign up anywhere, and there is no tracking. Your location is used only to show what you see on screen. Your trips stay on your phone and in your private iCloud account, readable only by you. The only thing that leaves your phone is an occasional lookup of which street you're on, handled by Apple's own mapping service — and a GPX export, which only happens when you ask for it. Requires iOS 18 or later. The app needs location services for speed, position and direction. Motion & Fitness access is optional and uses the barometer for more accurate measurement of climb and gradient; without it, climb is measured with GPS.
