BMK THunter
ThermalHunter Sensor App
Free · Designed for iPad. Not verified for macOS.
New in 1.1: a high-contrast Sunlight theme you can read in bright sun, and a thermal tone that rises and falls with the air temperature, even with the screen locked.
BMK THunter turns the BMK ThermalHunter sensor into a thermal detector on your phone. The sensor measures the air temperature at your flying field and sends it over Bluetooth. The app shows every change the moment it happens, so you can spot a rising bubble of warm air and launch your model glider or aircraft at the right time.
SEE THE THERMAL COMING
• Live ΔT: a large readout shows how much the air has warmed or cooled compared with your reference, always with a + or − sign.
• Scrolling graphs of air temperature, and of air pressure and wind speed when the optional wind sensor is fitted.
• Re-centre the reference with one tap, reset the graph, and choose a separate scale for each graph.
• Dynamic time range: pinch to zoom from the last minute out to the last 30 minutes, and drag to look back.
HEAR IT WITHOUT LOOKING
• Thermal sound: a vario-style tone follows the temperature trend. Short beeps speed up and rise in pitch as the air warms, low slow tones sound as it cools, and it stays silent when nothing changes.
• Sensitivity follows the temperature scale you choose for the graph.
• Keeps working with the screen locked or while another app is open, and plays alongside your other audio.
BUILT FOR THE FIELD
• Sunlight theme: white, high-contrast screens designed for direct sun. A Night theme is available too.
• Colour-blind-safe graphs: lines differ in colour, width and end marker, so colour is never the only cue.
• Optional "screen always on" while you fly.
• A clear warning when data stops arriving, showing how old the last reading is.
SIMPLE CONNECTION
• Connects over Bluetooth Low Energy and reconnects to your last sensor automatically, including after a dropout.
• Shows the sensor's battery voltage and signal strength.
• Rename your sensor from the app.
Requires a BMK ThermalHunter sensor. Without a sensor, the app shows sample data only.
Ratings & Reviews
Version 1.1 brings a new look and a new way to find thermals.
• Thermal sound: a vario-style tone follows the temperature trend. Short beeps get faster and higher as the air warms; low, slow tones sound as it cools. Sensitivity follows the temperature scale of the graph. Switch it on or off from the top bar.
• Works in the background: data, sound and reconnection continue with the screen locked or while you use another app.
• New Sunlight theme: white, high-contrast screens that stay readable in direct sun. A Night theme is still available in Settings.
• Colour-blind-safe graphs: every line has its own colour, width and end marker, plus a legend.
• Larger ΔT readout with an explicit + or − sign.
• Automatic reconnection when the Bluetooth link drops, with a clear warning and the age of the last reading.
• Dynamic time range is now the default: pinch to zoom, drag to look back.
• Clearer device search screen and Bluetooth messages.
• Bluetooth and stability fixes.
