Precision Watch vs Magnetick

Is your mechanical watch running fast or slow? Find out in minutes. Precision Watch measures your watch's true daily accuracy by comparing it to atomic time — no expensive timegrapher and no trip to the watchmaker. Start a measurement, come back later, enter what your watch reads, and see exactly how many seconds per day your watch gains or loses. WHY PRECISION WATCH • Atomic-accurate — every measurement is referenced against an atomic clock • No microphone guesswork — a reliable, repeatable method that actually works • Track every watch — build your collection and follow each one's rate over time • Fast & beautiful — a clean, native experience made for watch lovers • Private — everything stays on your device, no account required HOW IT WORKS 1. Sync your watch to the on-screen atomic clock 2. Wait — from a few minutes to several hours, your choice 3. Enter what your watch reads now 4. Get your precise +/- seconds-per-day result Know when your watch truly needs a service — and when it doesn't. Stop guessing and start measuring. Precision Watch Pro unlocks unlimited saved measurements and your full watch collection. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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 — the same sensor your compass uses, but exposed in a way you can actually read and interpret. KEY FEATURES • Live magnetic field reading — a single, easy-to-read number, updated in real time • Guided mode — Magnetick stabilizes its baseline, then tells you plainly when something nearby is affecting the field • Real-time chart — watch how the field changes as you move your phone around an object • 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 • 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 — 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.
