A camera filter app for iPhone. Three effects: a heat-map thermal look, an x-ray look, and a ghost detector.
Thermal FX does not measure temperature. iPhone has no infrared sensor. The app re-colours the ordinary camera image by brightness — it is a look, not a measurement. Nothing in it sees through walls, objects or clothing, and the Ghost meter is a party effect, not evidence.
Because there is no sensor that could produce one. Real thermography needs hardware your phone does not have — a FLIR One or Seek Compact attachment. Any app that shows you degrees from the plain camera is making them up. This one gives you the look, done properly, and says so.
The thermal effect maps brightness across the palette, so it needs a scene with a range of brightness. Point it at a person or a warm object in a dimly lit room rather than at a flat, evenly lit wall. The intensity slider controls how hard the range is stretched.
Two real inputs: how much the image changed between frames, and the sound level from the microphone. That is genuinely all it is. Wave at the camera or make a noise and it moves.
