DarkSpeed vs Speedometer Ultra

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.

Measure, record and track your speed wherever you’re moving with Speedometer Ultra, the all-in-one GPS speedometer, HUD and trip logger for iPhone. From a morning ride to a highway drive, a hike to a harbor crossing, Speedometer Ultra makes it easy to see your speed, stay aware of the limit and keep a detailed record of every journey. Precision Speed, Wherever You Go: Read your speed straight from your iPhone’s GPS, without installing or calibrating a wheel sensor. Choose from nine modes – walking, running, cycling, driving, motorcycle, truck, train, boat and plane – each with a gauge scaled to the speeds you expect. Display speed in mph, km/h or knots. When the signal isn’t good enough to trust, Speedometer Ultra shows – rather than a guess. Stay Under the Limit: Set a speed limit and see it clearly on the gauge. Cross it and the app warns you with a chime and a tap, helping you stay informed without taking your attention off the road. Turn the sound off if you prefer a visual warning, and keep recently used limits one tap away as the road changes. Record the Whole Journey: Start recording to save your route, distance, average moving speed, maximum speed, moving time, elevation, average temperature and a graph of your speed throughout the trip. Any time without reliable location data is shown as a signal gap, so you can judge how completely the journey was measured. Rename trips, add notes and export the underlying route data as CSV. Trips stay on your device and sync privately through your own iCloud account. Keep the Journey in View: Follow your position on a live map while keeping your speed front and center. Switch between north-up and heading-up, pan freely, or use the compass, altitude, temperature and time until sunset for more context. While recording, time, distance and average speed remain on the Lock Screen and in the Dynamic Island, with a Stop button that works without reopening the app. Use HUD at Night: Switch to a large, high-contrast heads-up display for a speed reading you can take in at a glance. Mirror it when you want the reflection in the windshield to read the right way around, or leave it as it is and keep your iPhone on the dash. The screen stays awake while the app is open. Download now and use the GPS speedometer, nine movement modes, live map, compass, speed limits and trip recording for free. Choose PRO to unlock HUD mode, live and recorded speed graphs, and CSV trip exports. GPS accuracy and availability depend on your device, surroundings and signal conditions.
