CycleHUD
Eyes on the road. Radar on your wrist.
A clean, radar-first cycling HUD for iPhone and Apple Watch. See vehicles approaching from behind on a glanceable radar lane, feel escalating wrist alerts as they close in, and finish every ride as an Apple Health workout.
🚧 In testing — coming to the App StoreWhat it does
Built around the Coospo TR70 rear radar (and Garmin Varia–compatible radars).
Rear radar lane
Vehicles behind you are plotted by distance on a perspective lane that glows amber → red as a car closes in.
Apple Watch wrist alerts
A tap for each new vehicle, escalating as it nears, and a distinct buzz if the radar drops out — eyes stay on the road.
Reliable presence
Uses the radar's heartbeat to confirm it's really there, and clearly shows NOT CONNECTED the moment it isn't.
Live ride metrics
Speed, average, distance, time, cadence, ascent, heart rate and calories — at a glance.
Apple Health workout
Each ride is saved as a cycling workout with distance, duration, calories and GPS route — or keep rides local-only with one toggle.
Ride summary & history
Finish with a clean summary over a map of your route, and reopen any past ride from Settings.
Vehicles on the map
Every vehicle the radar flags is pinned on the ride map, so you can see where traffic came up behind you.
Heart-rate warning
Set a max heart rate and get a red readout and a distinct wrist buzz the moment you cross it.
Battery, light & landscape
See the radar's battery on the panel, switch between light and dark, and flip to a side-by-side landscape layout when you want it.
Private by design
No accounts, no servers, no tracking. Your ride data stays on your device and in Apple Health.
Made for the ride
A radar-first screen with the data that matters, and nothing that doesn't.
The whole panel floods with colour and your wrist taps faster as a vehicle approaches, so you always know what's behind you without looking down. Speed comes from your wheel sensor or GPS, elevation from the barometer, and heart rate from your Apple Watch.
Privacy
CycleHUD is built to keep your data on your device.
CycleHUD has no accounts and no servers. It does not collect, transmit, sell, or share your personal data, and contains no analytics, advertising or tracking. Location, motion, Bluetooth-sensor and heart-rate data are used only on your device to power the ride display and to save your workout to Apple Health, which you control.
