iPhone Screenshots



Use your iPhone to find nails in wooden support beams within your wall, or any sort of magnetic metal hidden from view.

For this app to work, the nails in your wall should be magnetic and your device (iPad, iPhone or iPod) should have a built-in magnetometer. This app does not detect non-magnetic objects, For example, aluminum or wood studs.

DISCLAIMER: The performance of the app is limited by the construction of the wall, presence of a phone cover and/or the material of the nails in the studs.


If your device has a external case, please remove before using this app.

Calibrate your device’s magnetic sensor by moving the device in a "Figure 8" pattern. Then tap the "Intensity" reading displayed on the app to set the baseline to zero.

To accurately detect nails using this app, on iPhone 5s and below, sweep with the right edge of the device against the wall. For iPhone 6 and above, sweep with the top edge of the device along the wall.

Sometimes it helps to first figure out the location of the magnet (compass magnet) on your phone using a magnetic material so it becomes clear where to "mark" when you find a nail in the stud.

Does find metal objects, screws or nails

I needed help finding studs while putting up a cabinet in the bathroom. When you pass the phone along the wall it will identify any metal objects using the iPhone's magnetometer close to the surface. I believe all iPhones have one which is also used when you use your compass app. I suggest that you test a real object to see where the sensor is on your phone which is approximately toward the upper half of the back of the phone. The sensor is sensitive and my be slightly off a half and inch or so off, so move it around to identify where the real peck is. As you identify objects, mark them with a pencil and see if they form aligned with any others. These are most likely the screws in the studs. Draw a straight line vertically and this should identify the stud. One area that I thought was the peak wound up not having a stud but moved the hole over a couple inches the the left and it worked.

happy shelves ,

Total life saver!

After many weeks of planning, my boyfriend end and I were finally putting shelves on my walls. We started drilling before thinking about studs. We ended up hitting one and (obviously) not being able to hang the shelves. Before I was able to really be upset out about it, my boyfriend thought to download this app to help with our project instead of going out and buying an actual stud finder. After playing around with it, i feel confident in saying this app really does works!!!!

I have an iPhone 8, and I believe the phone starts detecting metal right at the center of the phone (where the Apple is). The trick is to start from one extreme of the wall and move SLOWLY to the other. The meter will detect the beginning of a stud when it reads 60, rise in numbers, and detect the other edge of the stud when it goes back down to 60. The length between the two 60’s should be either 4 or 6 inches, since that’s how wide studs usually are. In other words, if you’re marking the beginning and the end of a stud, mark when the detector reads 60 once and then again. FYI, studs are places 16 inches apart from each other.

Blame fire ,

You might doubt me but it really works

I have tried using this app on most of my household items. It can detect metals 100%. I have to admit that it is a little tricky as to what part of your phone you have to use to make it work. However, I have figured it out. That's sweet spot is at the center of your phone right below your lens and next to the power button. I figured it out by using a pair of scissors and using only the point of entry point to the phone to see where the sweet spot is. I still can't figure out how this app actually works or maybe the phone really has a magnet. I also noticed that it doesn't work on any metal. It works on metals that can actually be magnetized. I tried it on my father stainless steel watch at detected nothing. However, when I tried it on the refrigerator or the oven it works hundred percent. It is very nice keep up the good work. Maybe at some point in the future you can add more features to it.
