01 / VISION
Read intensity at a glance.
A calibrated relative change drives the full-screen color field: lower change stays cool; stronger change moves toward warm red.
ON-DEVICE FIELD INSTRUMENT
Magnetic change,
made visible.
Magnetic Vision turns the iPhone magnetometer into a responsive color field, anchors measured samples in AR, and records raw values for closer inspection.

THREE VIEWS · ONE SENSOR
Inspect the same signal
from three angles.
Every view starts with the magnetic-field vector measured at the iPhone. The app changes how the reading is presented—not what the sensor can detect.
02 / AR FIELD
Leave measured samples in space.
AR world tracking anchors translucent samples where readings were taken. Unsampled space remains clear; no field geometry is invented.
03 / DATA
Keep the numbers.
Inspect X, Y, Z, total magnitude, noise, peak, and sampling behavior. Record timestamped sessions locally and export CSV when you choose.
MEASUREMENT METHOD
Reference. Move. Repeat.
Reliable comparison comes from controlled geometry—not a single dramatic peak. Set a reference, move slowly, keep orientation consistent, and repeat the pass.
- 01Set a reference
Hold the iPhone still, away from the object being compared.
- 02Control the path
Keep distance, angle, speed, and accessories as consistent as possible.
- 03Compare repeats
A repeatable spatial pattern is more informative than one isolated value.

SCIENTIFIC LIMITS
A signal is not an identity.
Nearby metals, magnets, electric currents, electronics, accessories, the iPhone itself, and environmental fields can all affect a reading. Magnetic Vision cannot identify a source or reliably distinguish electrical wiring from other materials.
It is not a calibrated surveying, electrical-safety, medical, or drilling-safety instrument. Do not rely on it to decide where drilling or electrical work is safe.
SUPPORT
Start with a clean measurement.
Most unexpected readings come from permissions, accessories, movement, or an unstable AR session. These checks resolve the common cases.
mail@cishor.com01 A feature is unavailable
Open iOS Settings and grant Magnetic Vision access to Camera and Motion.
02 AR tracking will not settle
Start in a well-lit area and move the iPhone slowly while AR establishes the room.
03 The scene fills with samples
Raise the minimum threshold so only stronger measured changes are anchored.
04 Values seem unexpectedly high
Remove magnetic cases and accessories, move away from electronics, then reset the reference.
