Bike Radar shows و sounds what شما rear bike radar sees, on top of whatever برنامه you are already running. A thin strip down the edge of the screen shows each approaching vehicle's distance, closing speed و lateral position. Tiered beeps rise as the closest vehicle gets nearer, و a distinct urgent tone fires when an impact looks imminent - شامل while you are rolling slowly toward a junction با a سریع vehicle behind. A clear chime sounds when the radar sees nothing left within شما alert distance. Everything runs on گوشی شما: بدون حساب کاربری, no cloud, no analytics. The optional Home Assistant integration publishes ride stats to شما own server و nowhere else. Another برنامه on شما phone can ask to use شما radar, و nothing reaches it until you allow it on a screen naming the برنامه; that handover happens on the device, برنامه to برنامه. Features: - Live overlay با per-vehicle distance, closing speed و lateral position - Tiered proximity beeps, urgent imminent-impact tone, همه-clear chime - Post-ride summary اعلان: overtakes, close passes, distance, tightest pass - Front دوربین/light auto mode by local sunset (one coarse location read per ride) - Bosch Smart سیستم eBike telemetry, strictly read-only - Walk-away و forgot-to-lock یادآورها - Optional Home Assistant publishing: batteries, close passes, ride summaries - Sharing با another برنامه on شما phone (با شما permission): the radar feed, و if you also allow it control of شما tail light و hiding the overlay - Optional on-device capture log برای diagnostics, off by default و never uploaded - English و Spanish Requires a پشتیبانی می‌کند ازed rear radar paired over Bluetooth (pair it once in سیستم تنظیمات) و Android 12 or newer. There is no standard Bluetooth profile برای bike radars, so support is per model; the compatibility list on the project's source page says which units work, و the list is short. A radar that reports distance only is expected to get the approach beeps, the همه-clear و an overlay coloured by distance; the per-vehicle speed و side readouts, the urgent tone و close-pass counting need one that also reports closing speed و lateral position. The radar, دوربین و eBike integrations degrade gracefully: each کار می‌کند باout the others. Bike Radar is a riding aid, not a safety guarantee.
