CycleHUD

CycleHUD turns your rear radar into a clear, glanceable heads-up display, so you always know what's coming up behind you without taking your eyes off the road. Vehicles approaching from behind appear on a clean perspective lane, nearest at the top, and the whole panel glows amber to red as a car closes in. A green "Clear" shows when the road behind is empty. Pair an Apple Watch and you'll feel it too: a tap for each new vehicle, faster as it nears, and a distinct buzz if the radar ever drops out. Eyes up, hands on the bars. BUILT FOR THE RIDE • Rear-radar lane, colour-coded by how fast and close a vehicle is • Apple Watch wrist alerts that escalate with proximity • Optional new-vehicle beep through the phone • Live metrics: speed, average, distance, time, cadence, ascent, heart rate and calories • Every ride saved as an Apple Health workout (optional) • Ride summary and history with a map of your route • See exactly where vehicles passed you, each pinned on the map with distance and speed to review afterwards • Heart-rate warning that flashes the display and buzzes your wrist • Light or dark theme, plus a fixed-landscape layout for your handlebars WORKS WITH YOUR SENSORS Built around the Coospo TR70 rear radar, and also works with Garmin Varia-compatible radars and standard Bluetooth speed and cadence sensors. Speed falls back to GPS when no sensor is connected. PRIVATE BY DESIGN No accounts. No servers. No tracking, ads or analytics. Your location, heart rate and ride data stay on your device and in Apple Health, which you control. CycleHUD is a focused, no-nonsense tool made by a rider who wanted exactly this, and nothing more.
