## What is FieldSweep?

Behind the fridge. By the breaker panel. Now you have a number.

FieldSweep turns your phone's magnetometer into a calm analog meter.
Walk around a room, watch the needle move, and record the peaks with
a place name — so "it feels strong here" becomes "126.8 µT, behind
the fridge, last Tuesday."

MEASURE
- A paper-white dial with a real needle, 0 to 200 µT
- A 60-second trend line under the dial
- Guided figure-eight calibration keeps readings meaningful

RECORD
- Capture the recent peak with one tap
- Name the place: kitchen, desk, breaker panel, or your own words
- Sort your readings by time or by strength

HONEST ABOUT ITS LIMITS
- It measures magnetic flux density only — not electric fields,
  not Wi-Fi, not cellular signals
- It makes no health claims and no safety judgments, ever
- Earth's own field is roughly 25–65 µT; the app says so on the dial

PRIVATE BY DESIGN
- Readings and place names stay on your device
- No account, no cloud, works completely offline

One purchase, everything included, forever.
