Magnetick vs Chronograde

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.

Know your watches beyond a single reading. Chronograde brings together microphone-based estimates, manual drift records and your collection history. FREE TO START Keep an unlimited watch collection with photos and details. Use the Timegrapher for acoustic rate and beat-error estimates, save up to 10 manual readings, and complete one guided Regulation Coach run. iCloud sync and JSON backup remain free. UNDERSTAND THE READINGS Acoustic results depend on the watch, microphone placement and background noise. Manual readings compare displayed watch time with a network reference or the labeled device-clock fallback; timing and reference errors affect the result. Estimates do not replace professional testing. COMPARE SESSIONS (Chronograde Pro) Compare two manual sessions by observed daily rate, reading count, elapsed coverage and recorded positions. Preview and share a comparison PDF. A difference does not prove a service effect. WEAR & SERVICE (Chronograde Pro) See distinct logged days per watch over 30, 90 or 365 days. Days without entries mean not logged. Keep wear and service records with provider, cost and notes. PRIVATE REPORTS (Chronograde Pro) Choose watches, history and a date range, then preview and share a PDF. Serial numbers, notes, amounts and photos are excluded by default. A report is not a backup, appraisal or certification. MORE HISTORY (Chronograde Pro) Record unlimited manual readings and sessions, explore rates by position and repeat guided Regulation Coach runs. REFERENCE & EXPORT (Chronograde Pro) Use a large reference clock with available network time correction. Import watches from CSV and export records to CSV or Excel.
