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 (ΞT) using your device's built-in magnetometer â the same sensor your compass uses, but exposed in a way you can actually read and interpret. KEY FEATURES âĒ Live magnetic field reading â a single, easy-to-read number, updated in real time âĒ Guided mode â Magnetick stabilizes its baseline, then tells you plainly when something nearby is affecting the field âĒ Real-time chart â watch how the field changes as you move your phone around an object âĒ Built-in sensor map â 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 âĒ Beautiful dark interface designed to be readable at a glance WHO IT'S FOR âĒ 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 â 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.
Bathyal

Bathyal is a clepsydra â an ancient water clock â rebuilt for the deep sea. In the bathyal zone there is no day or night. No sunrise, no shadow, nothing to set a clock by. The only light is made by living things. Bathyal is the instrument that keeps time down there: a face of glowing concentric channels where every drop is a second, and time is material. Watch it work: âĒ Each second forms as a drop at the heartbeat and joins the ring âĒ A full ring of seconds distills into one minute â and pours, visibly, down into the next channel âĒ Minutes pour into hours, hours into the day's two halves, days into months â at midnight the whole cascade runs at once âĒ Once a year, the last drop of December sinks past the digits into the abyss, unmeasured Make it yours: âĒ Solid bands or beaded drops, sweeping or pulsing motion âĒ 24-hour or 12-hour time â 12-hour splits the hours at the meridian into a morning ring and an afternoon ring âĒ Calendar rings for the month and year, or a Monday-first week ring whose weeks are spent, not kept âĒ Run the midnight cascade demo any time from the settings On your wrist: âĒ A full-screen water clock for Apple Watch â seconds, minutes, and hours in the same adjacent channels âĒ Add Bathyal as a complication; the live rings sit on any face and rewrite themselves as the day moves. No two times look the same â that is the instrument, not a hand on a circle âĒ Hold the Watch face for settings. Pulse or sweep, 12- or 24-hour time, and an optional Monday-first weekday ring. Hours, motion, and the week calendar also travel from the gear on iPhone On the Lock Screen: âĒ Add Bathyal as a Lock Screen widget â live rings, a different pattern for every minute, the same figure as the Watch complication âĒ Hours, motion, and the weekday ring follow from the gear Quiet by design: âĒ Completely free, no accounts, no ads, no tracking â it never connects to anything âĒ Works fully offline âĒ Keeps the screen awake on a desk or bedside table If the instrument keeps good time for you, you can send a drop â a small tip â and the face answers with the benefactor tinctures: other colors of bioluminescence, and a single grain of sand set on the seabed of the dial. Drops become months.

Verdict
The clearest difference is in-app purchases: Magnetick at none against Bathyal's 3. On price, ads, device support and iOS requirement there is nothing between them.
