Monitor every tire with confidence.

The home screen shows pressure, temperature, sensor battery voltage or low-battery status, the last received time, and data freshness for every tire position.

Choose the standard card view or dashboard view. Pressure can be displayed in PSI, Bar, or kPa, and temperature in °C or °F.

• The last valid reading remains visible when reception is temporarily interrupted and is clearly marked as old.
• A tire that has never produced a reading is shown differently from one with stored readings that are temporarily stale.
• Spare tires keep their own sensor, readings, history, and alerts.

Hyphoon classifies abnormal conditions by urgency. Level 1 calls for attention, such as a possible slow leak or low sensor battery. Level 2 recommends prompt inspection for low pressure, high pressure, or high temperature. Level 3 recommends slowing down and stopping safely for a rapid leak, severe pressure abnormality, or extreme heat.

• Alerts can use system notifications, vibration, three distinct sounds, localized voice warnings, or sound and voice together.
• While a condition continues, Level 3 repeats about every 2 minutes, Level 2 every 5 minutes, and Level 1 every 20 minutes.
• Mute one tire for 15 minutes, 1 hour, or until it returns to normal. Normal readings automatically resolve the event.
• An audio queue prevents warnings from talking over one another when several sensors are abnormal.
• Low sensor battery is maintained as a separate service reminder and is not misclassified as a pressure event.

The app can continue receiving compatible BLE sensor broadcasts while it is in the background. Android uses a foreground monitoring service; iOS uses Bluetooth background capability and local notifications. Reopening the app synchronizes the latest saved readings and history samples.

Create multiple independent vehicle profiles. Each vehicle can have its own name, sensor assignments, alert limits, history, and parking location.

Built-in layouts include bicycle, motorcycle, delta trike, tadpole trike, passenger car, and custom vehicle.

• Custom layouts support up to 6 rows and 12 road tires, ordered from front to rear.
• Each row can contain one center tire, one tire on each side, or dual tires on both sides.
• Add a separate spare tire without counting it as a road position.
• Rename vehicles and tire positions, and swap two sensor assignments after tire rotation without deleting the vehicle.
• Layouts can cover passenger cars, motorcycles, bicycles, trikes, trailers, motorhomes, light commercial vehicles, and some multi-axle vehicles.

Open a physical tire position and assign its compatible sensor by scanning the sensor QR code, scanning for nearby BLE sensors, or entering the sensor ID manually.

• The same sensor cannot be assigned to more than one tire position.
• Unbind or replace one sensor without affecting the other positions.
• Use the swap function after tire rotation so the bindings follow the physical tires.

Set global default limits or override them for an individual vehicle. Low-pressure, high-pressure, and high-temperature thresholds are configured separately, including high-pressure ranges used by trailers, motorhomes, and some light commercial tires.

Each tire position stores about 14 days of detailed readings. Review pressure, temperature, time, and sensor-status changes. The activity page records pressure alerts, tire events, sensor assignments, and app-status changes, with filters for vehicle, event type, and date.

• Repeated warnings are grouped into one event and marked resolved after the tire returns to normal.
• A 7-day summary compares pressure converted to a 20°C reference value.
• The trend can be stable, slightly decreasing, possible slow leak, or still collecting data.
• The app shows data coverage and confidence and does not diagnose a slow leak when there is not enough data.

Export today, the last 7 days, the last 14 days, or a custom date range in CSV or JSON format. Export the current vehicle, all vehicles, or one tire position from its reading history. Android and iOS can save the file or open the system share sheet.

Android Auto can show all tire positions for the current vehicle, pressure, temperature, status, freshness, sensor ID, battery information, and 20°C reference pressure. You can switch vehicles and acknowledge or temporarily mute an active alert. Configure vehicles and sensors on the phone while safely parked.

CarPlay can show the current vehicle, tire status, pressure, temperature, update time, stale-data status, and allowed tire-pressure notifications, with vehicle switching.

Android and iOS widgets show the current vehicle status, key tire pressures, and alert state. Alert colors follow their severity; stale readings use a subdued style and never appear as a current normal reading. Tap the widget to open that vehicle.

Widgets follow the app language, units, vehicle name, and tire-position names.

Save a parking location manually for each vehicle. The app reads location once only when you tap Save now, can open navigation to the saved point, and lets you delete the record for one vehicle. It does not continuously track the vehicle or the user.

Hyphoon supports English, Simplified Chinese, Traditional Chinese, Japanese, German, French, Spanish, Italian, Portuguese, Dutch, and Polish.

• No account is required, and core monitoring does not require a cloud service.
• Vehicles, sensor assignments, and history are stored on the device. Tire-pressure data is not uploaded.
• BLE monitoring and local alerts continue to work without internet access.
• Location is used only when you actively save a parking position and for Bluetooth permission requirements on some older Android versions.

Hyphoon currently requires Android 7.0 or later, or iOS 13 or later, plus a compatible Hyphoon BLE tire-pressure sensor and a phone with Bluetooth Low Energy.

• Turn on Bluetooth and grant the necessary system permissions.
• Keep the phone within effective sensor reception range.
• On Android, allow background operation or disable excessive battery restrictions for Hyphoon when required by the phone manufacturer.
