Hyphoon is a companion app for compatible Bluetooth Low Energy tire pressure monitoring sensors. View pressure, temperature, battery status, and sensor activity in one clear dashboard for cars, motorcycles, trikes, and custom vehicles. KEY FEATURES • Monitor compatible BLE TPMS sensor broadcasts • See pressure and temperature for each wheel • Configure per-vehicle pressure and temperature limits • Receive local notifications and optional voice alerts • Review recent readings, activity, and tire trends • Use Home Screen widgets for at-a-glance status • View supported driving information through CarPlay • Bind sensors manually or by scanning a QR code • Save an optional parking location when you choose • Contact support directly in the app PRIVACY BY DESIGN Hyphoon does not require an account and contains no advertising, analytics, or cross-app tracking. Vehicle settings, sensor bindings, and tire readings are stored locally on your device. When you submit an optional support request, the information you provide and any selected attachments are sent to Hyphoon support. Diagnostic information is included only when you choose to attach it. IMPORTANT Hyphoon is a supplemental monitoring tool, not a replacement for manual tire inspections. Follow your vehicle placard or owner's manual for recommended cold tire pressure. Background reception depends on iOS scheduling, Bluetooth state, radio conditions, and compatible sensor behavior.
