Is your watch
magnetized?
A magnetized hairspring can throw a mechanical watch off by minutes a day. Magnetick turns your iPhone into a pocket magnetometer so you can check any watch in seconds — quiet, offline, and made for hobbyists who'd rather know than guess.
Guided check
Clean, or magnetized?
Set a baseline against the ambient field, then hold your watch up to the back of your iPhone. Magnetick tells you, in plain words, whether the case is pulling on the field around it.
Your watch is in the clear
The reading sits within a few percent of the ambient baseline — no measurable magnetism on the case.
Time for a trip to the demagnetizer
A clear deviation means the case is magnetized — a likely suspect when a mechanical watch starts running fast.
Built-in guide
Know where to hold the watch.
The magnetometer sits in a different spot on every iPhone — and a few centimeters off can mean a missed reading. Magnetick detects your model and points to the exact place to rest the watch, sourced from public iFixit teardowns.
- Auto-detects your iPhone model
- An on-screen overlay shows where to rest the caseback
- Searchable index covering every supported iPhone
The whole app
One job. Done well.
Live μT readings
Taps your iPhone's built-in magnetometer through Core Motion and reports field strength in microtesla — straight from the sensor.
30-second chart
A rolling chart traces the last 30 seconds, so you can see exactly how the field changes as you bring the watch closer.
Stable-reading hint
Magnetick highlights when the signal settles, making it easier to tell a steady value from environmental noise.
Fully offline
No network requests. Use it on the bench, on a plane, or in a watchmaker's back room — works without a connection.
No data collection
No accounts, no analytics, no advertising, no trackers. Readings never leave your device.
Honest about limits
A hobbyist tool, not a calibrated instrument. Perfect for spotting a magnetized watch — not for safety-critical work.
