Magnetick vs Magnetic Sensor
Price, ratings, monetisation and update history for both apps, side by side ā with what reviewers say about each.
Magnetick
Read full descriptionHide 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 (μT) using your device's built-in magnetometer ā the same sensor your compass uses, but exposed in a way you can actually read and interpret. KEY FEATURES ⢠Live magnetic field reading ā a single, easy-to-read number, updated in real time ⢠Guided mode ā Magnetick stabilizes its baseline, then tells you plainly when something nearby is affecting the field ⢠Real-time chart ā watch how the field changes as you move your phone around an object ⢠Built-in sensor map ā 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 ⢠Beautiful dark interface designed to be readable at a glance WHO IT'S FOR ⢠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 ā 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.
Magnetic Sensor

Magnetic Sensor turns your phone's built-in magnetometer into three precise tools: ⢠Compass ā A live, tilt-compensated compass with cardinal direction (N/E/S/W) and adjustable magnetic declination so the needle points to true north, not just magnetic north. ⢠Metal Detector ā Set a baseline reading anywhere, choose Low/Med/High sensitivity, and feel haptic pulses that get stronger as the field deviates. Perfect for finding studs in a wall, screws under drywall, or rebar in concrete. ⢠Field Logger ā Record samples at up to 60 Hz, then export to CSV via the share sheet. Saved recordings stay in the app for replay or re-export. KEY FEATURES ⢠Live X / Y / Z axis readings + total field magnitude ⢠Tilt-compensated heading using the accelerometer ⢠Magnitude history sparkline + multi-channel chart ⢠Rolling statistics: mean, standard deviation, RMS, range ⢠Figure-8 calibration helper with quality indicator ⢠Min / Max tracking with one-tap reset ⢠Three sample rates: Slow (500 ms), Normal (100 ms), Fast (16 ms) ⢠Light / Dark / System theme ⢠English and Korean ⢠Unit options: μT, mGauss, nT ⢠Adjustable smoothing ⢠Magnetic declination presets ⢠Haptic alerts for the detector ⢠Keep-screen-awake while recording ⢠CSV export with full timestamp + per-axis data PRIVACY All sensor data is processed on-device and never leaves your phone. The app does not collect location, contacts, or personal information. Anonymous mobile advertising is used to keep the app free; you can watch a rewarded ad to unlock unlimited CSV sharing for the session. WHO IT'S FOR ⢠Hobbyists exploring magnetic fields ⢠DIYers detecting screws, studs, and rebar ⢠Students collecting data for physics or geology projects ⢠Hikers wanting a reliable phone compass ⢠Anyone curious about the invisible field around them REQUIREMENTS A device with a magnetometer (most phones built since ~2013). The app cannot work on devices without one ā it will tell you on launch.

Verdict
The clearest difference is ads: Magnetick at none against Magnetic Sensor's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.
