Impossible
Impossible to calibrate, i even went outside and away of any magnetic field, like literally just and outdoor wood table on top of grass, and still gave me the error message. Not sure how it is working for some, but I am deleting and moving on
This app helped me solve my problem
One of my watches was gaining a fairly good amount of time randomly one morning after traveling for work. To rule out whether I needed to have service performed, I wanted to first check for magnetization.
The easy steps provided in the app worked great.
I determined my watch was magnetized, bought a demagnetizer, verified it was no longer charged on the app after demagnetizing, and now the watch is back to running at -1/-1.5 seconds per day.
Highly recommend this for its simplicity. Straight up helpful and a good product.

Great app
Works great ! Thank You
Effective and easy to use
Does what it says on the tin
It works
Some of my watches needs to demagnetise :(
Very useful
It doesn‘t deserve the 3 stars. If you calibrate properly, the app works perfect!
Read the instructions
Great app, can’t understand some negative reviews. Works perfectly if you read the instructions
Detect Iron
iPhone 15 pro, IOS 18.7.1, The App detect iron. No more and no less. Test with tweezer and compass, compass is quiet, App show magnetized. App is useless. And yes, calibrate and recalibrate...
it works! must have app for watch owners.
This app works on my iPhone 16 pro. After calibration, put your watch close to the bottom half of the phone’s screen.
I tried it with my Hamilton and Luminox watches and they weren’t magnetised.
But when I tried with my Citizen titanium watch, the app showed it was slightly magnetised.
I then brought a strong magnet close to the phone and the app detected strong magnetism from 30cm away.

Brilliant
I think this may be the perfect app for detecting magnetism is watches. The fact that it can be calibrated for accuracy makes it a slam dunk.
If you understand that almost all ferrous metals contain some level of magnetism, due to the magnetic domains in the metal, then you understand why this app is so powerful.

Very Useful - Works Great
Really can’t understand some of the negative reviews on this App.
Was concerned that my watch had become magnetised and after learning of this App dowloaded it.
It indicated that the watch was magnetised so used a demagnetiser you can buy quite cheaply on the Internet.
In checking the watch again the App showed it was no longer magnetised.
Have subsequently tested it with other metal items and this App really does work.
Highly recommended for all those who wear mechanical watches.

Works
Just follow the instructions and this app will be able to detect magnetism in your watch. I have used it on several watches
Works well for me
Make sure to calibrate and keep it steady when measuring
Professional watchmaker review
What can I say other than works great! Thanks for making this app, I wouldn’t hesitate to recommend it to people 😄
Useless
All it does is repeatedly come up “Recalibrate” when you press the “Calibrate” function. After 4-5 attempts, got bored and deleted app.
Woks well!
Thank you for making this app easy to use, functional and free! 🙌
Fake
Put anything metal next to that blinking dot, and it will register it “magnetized”. This is extremely wrong and inaccurate waste of time
Misleading
I would caution how you use this app.
If you bring ANY ferrous material near the phone’s compass sensor, it will detect magnetism, regardless of if it is magnetized or not. The app measures changes in magnetic field strength, which is not the same as measuring magnetism. It is simply detecting if there is something that affects the magnetic field strength. Even after demagnetizing several small screws, tweezers, and watches, this app detects them as magnetized, even though none of them are. You will get many false positives if you bring a ferrous item in close proximity to the sensor area.

Look no further than…
This is a great app, easy to use and works well …
Best I've found
What a clean and easy to use app! Works great, far better than others I've tried. Thanks!
