Bike Guardian

About this app

Bike Guardian turns the phone already on your handlebars into a cyclist-assistance companion. SITUATION WARNINGS - Object boxes are context, not warnings. - A rider warning requires a tracked vehicle that is measurably closing over time. - Visual, spoken, and haptic feedback share one typed situation identity. - Uncertain car, truck, bus, or motorcycle subclasses are conservatively called vehicle. REAR GUARD - Uses your phone cameras to watch the road behind while you watch the road ahead. - Warns with "vehicle approaching behind" or "fast vehicle approaching behind" only after temporal closing evidence. - Supports handlebar and seatpost mounting on devices with simultaneous front and back camera capture. LOCAL EVIDENCE - Warning transitions and numerical evidence are stored locally. - Possible pass events inferred from image motion remain explicitly unverified. - Unverified pass candidates never become automatic community map facts. - Raw video sharing is off unless you explicitly opt in. IMPORTANT Bike Guardian is a rider-assistance tool, not autonomous control. It does not replace your attention, judgment, or local traffic law. Silence is not proof that the road is clear.

- Added an independently licensed, on-device production vehicle detector using Apple's checksum-pinned Core ML model. - Connected rider-confirmed community hazards to the production service with offline retry and server-enforced access controls. - Kept visual boxes as context while tracked closing motion remains required for rider warnings. - Improved release checks so every shipped build must contain the approved detector and exclude development-only models.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
