About

Magnetick

Read full description

Magnetick turns your iPhone into a precision magnetic field meter. If you've ever wondered whether your watch, tools, or jewelry have become magnetized, Magnetick gives you a clear, glanceable answer in seconds. Hold your iPhone near any object and Magnetick reads the surrounding magnetic field in microtesla (ΞT) using your device's built-in magnetometer — the same sensor your compass uses, but exposed in a way you can actually read and interpret. KEY FEATURES â€Ē Live magnetic field reading — a single, easy-to-read number, updated in real time â€Ē Guided mode — Magnetick stabilizes its baseline, then tells you plainly when something nearby is affecting the field â€Ē Real-time chart — watch how the field changes as you move your phone around an object â€Ē Built-in sensor map — Magnetick knows where the magnetometer chip sits inside your specific iPhone model, so you can hold the right part of the phone close to what you're testing â€Ē Beautiful dark interface designed to be readable at a glance WHO IT'S FOR â€Ē Watch owners checking whether their mechanical watch has been magnetized (a common cause of timekeeping errors) HOW TO USE 1. Open Magnetick and let the reading stabilize for a few seconds 2. Slowly move your iPhone close to the object you want to test 3. Watch the number — a sharp rise means the object is generating or carrying a magnetic field PRIVACY Magnetick reads only the magnetometer sensor and runs entirely on your device. No data is collected, transmitted, or stored. No accounts, no ads, no tracking.
