Indoor Humidity Predictor

Turn your iPhone into a pocket-sized hygrometer!

Indoor Humidity Predictor blends computer-vision, pressure analytics, touch latency and ambient-light scattering to give you an instant picture of the moisture in the air—no extra hardware required.



Why humidity matters
- Dry air (under 40 % RH) can dehydrate skin, irritate airways, warp guitars and crack wooden furniture.
- Humid air (over 60 % RH) encourages mold, dust-mites and sluggish thinking.


How it works
- Camera Fog Test – our most accurate method
- A micro-mist is briefly introduced to the lens; a neural network times dissipation to infer dew-point.
- Barometric Pressure Trends: Uses the built-in barometer plus local weather trends for a coarse baseline.
- Touchscreen Response: Dry air lowers skin capacitance; your tap-reaction profile helps refine estimates.
-Ambient-Light Scattering: Measures Rayleigh scatter to detect airborne particulate moisture.

Each sensor scores independently; our fusion engine ranks confidence in real time, then delivers a single percentage along with a simple verdict—Dry, Ideal or Humid—so you know exactly what to do next.

At-a-glance dashboard
- Live speedometer-style gauge (30-70 range)

Smart recommendations
After every test you’ll receive actionable tips:
- “Run a cool-mist humidifier for 2h.”
- “Move fiddle-leaf fig 1 m away from vent.”
- “Hang damp towels to boost RH by 5%.”
