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.
