Ensuring that a solenoid valve coil is working properly, or detecting a faulty one, is an important step in many repair or installation projects. Magnetic Tool makes testing a solenoid valve coil quick and easy. Just open the app, hold your smartphone up to the solenoid coil you want to test, and watch for the wheel in the app to start spinning. If it rotates, your solenoid valve is good to go.

If a solenoid valve is in a tough-to-reach space, you can also set Magnetic Tool to provide audio or haptic (or both) feedback when it detects a magnetic field. That way, you can check on a valve without seeing your screen, so you can maneuver your phone any way you need to.

Magnetic Tool has two modes: Simple and Advanced. With Simple mode, all you need to do is open the app and start testing—it's that simple. Advanced mode allows you to adjust the threshold tolerances of the magnetometer, which is most often used to reduce or eliminate interference from other nearby solenoid valves.

Magnetic Tool is part of the Danfoss CoolApps Toolbox, a collection of mobile apps designed to help installers and service technicians with their daily tasks. See the full collection at CoolApps.Danfoss.com.

User Reviews

User feedback shows Magnetic Tool can be handy for magnet-related tasks and can work well on older iPhones, with some praise for adjustable sensitivity and AC/DC discrimination. However, a large and recurring issue across reviews is instability on newer devices, particularly freezes on startup and app non-functionality on iPhone XS/XS Max and iPhone 11. Some users still report it works on older hardware. Feature requests include more magnet-focused options. Overall, device compatibility and reliability are the main concerns driving negative sentiment.

Pros

Handy and useful for magnet-related tasks.
Works on older iPhone models (e.g., iPhone 5 and 8+).
Adjustable sensitivity with AC/DC discrimination.
Enjoyable to use and elicits positive reactions when it functions.

Cons

Freezes on startup/main screen, especially on iPhone XS/XS Max.
Non-working on newer devices (XS/XS Max/11) due to compatibility issues.
General non-functionality; the app does not work across devices.

Recent reviews

picks up magnetic fields a little too well, i love the ability to change sensitivity and discern between AC and DC

Had an iPhone 8+ and the app worked great. I got a new iPhone 11 and now the app does not work at all.
