Doing renovations? Smoothening and repainting your walls? Or maybe even just putting up a picture frame? Don’t you want the best results for your home? Or maybe you have lost a precious earring? Misplaced your car keys? For all of this and more, stud finder apps are really the best!
What is a Stud Finder?
Simply put, studs are little pieces of wood or metal previously hammered into walls for various purposes, which may have been plastered over when their utility was over; however because they are unneeded presently, they may cause issues when you try to put in any extra fittings or even try to hammer into the wall to hang up a favorite photo. Here’s where a stud finder is extremely helpful. It helps you detect wooden or metal framing studs, any nails, any wiring, located behind the final walling surface, usually drywall, so that you can bypass or remove those wood or metal pieces when you are doing anything to your wall. Usually, stud finders are handheld and are of two types: magnetic stud finders and electric stud finders.
Magnetic stud detectors use magnets to locate metal in the walling material because the magnet is attracted to the metal. The attraction grows stronger as the magnet gets closer to the metal in the walling. On the other hand, electronic stud finders rely on sensors that detect changes in the dielectric constant of the wall.
What is a Stud Finder App?
Nowadays, most of our work gets done through the phone. Then why not make this tedious task of ensuring our walls are clear of unnecessary wood and metal debris much easier by using the phone?
For this purpose, various wall stud finder apps have been created that can be easily installed into your cellphone or smartphone. All you have to do is hold the phone up to the wall, which task gets even easier if you use your selfie stick, for the hard to reach places!
Do stud finder apps really work?
Like many old-fashioned stud finders, most stud finder apps are magnetic, meaning that they simply rely on the phone’s built-in magnetometer to locate metal objects inside walls. Most phones are equipped with magnetometers today.
Stud finder apps make use of modern smartphones’ magnetometer sensor to pinpoint the exact location of wall studs. A magnetometer detects the nails, screws, and joists that act as fasteners for studs. Because wood studs are fastened with metal nails and/or screws, these applications are able to pinpoint their locations.
Besides functioning as an alternative magnetic metal detector, the sensor is also used for compass apps in phones. It works by measuring magnetic fields and can determine the device’s orientation in relation to the magnetic north. It is also used with the accelerometer and the GPS unit to determine the device’s position. It is through the magnetometer that digital maps are auto-rotated based on orientation. Meanwhile, the accelerometer determines movement and the GPS determines position.
Since navigation became an essential feature for smartphones, magnetometers have also become a mandatory component. As with most of the trends in technology, magnetometers for phones have become smaller and cheaper, but more powerful and efficient. The price of a magnetometer has gone down from $1.50 per device to below $0.50, as production volumes have increased. In 2008, only 8.7 million phone units were manufactured with magnetometer sensors. In comparison, in 2017, 1.54 billion phone units were sold worldwide, with most of them containing magnetometer sensors.
So yes, they do work. You just need to follow some simple steps as directed in the apps and you’ll be good to go!
Free Stud Finder Apps
There are a variety of smartphone stud finder apps available today, most of which are easily downloadable from either the AppStore (for Apple device users) or the PlayStore (for Android users). Here’s our list for both Apple iOS users and for Android users.
What are the best stud finder apps for iPhone?
This app allows you to turn your device into a metal detector. It utilizes your device’s magnetometer or compass for searching magnets and metals. The app can also detect electromagnetic fields, as well as find studs and wiring on walls. Paid version on the AppStore.
The Metal Detector / EMF Meter is an app for detecting the electromagnetic field or EMF. This app utilizes the internal compass hardware of an iPhone or iPad. When detecting metals or EMF, raw data is shown and it can be recorded and sent to an email. Available for free on the AppStore with in-app purchases.
Electromagnetic Detector EMF is an app for identifying electromagnetic fields or EMF. Since iPhones and iPads have compasses, they are compatible with this app. The app has utilities like EMF warning, EMF Meter, metal detector and ghost detector. Available for free on the AppStore with in-app purchases.
Metal Detector by Alexandr Balyberdin is a free app for iOS devices in which you are able to detect any magnetic metal nearby. You can shake it to calibrate and it features great usability. It is a popular metal detector app. Available for free on the AppStore.
Smart Metal Detector is an app for detecting nearby metals. It utilizes your mobile device’s built-in magnetic sensor. Ferric metals and magnets are searchable with this app, ideal for stud finding, treasure hunting or even ghost hunting. Available for free on the AppStore with in-app purchases.
This app will allow you to find metal framing studs, nails or screws in walls: using the magnetic sensor of your phone, you will be able to find if there’s something in the wood, and display light in case the app find something metallic. Available for free on the AppStore with in-app purchases.
Using this phone and your app you will be able to find nails, studs, and wires within your walls. Just place your iPhone on the surface and this app will make sure to find any metallic item inside the walls. Available for free on the AppStore with in-app purchases.
Wall Stud Magnetic Detector by Gregorio Bello can be used to quickly detect wood studs hidden under walls, drywall, plasterboard, or stucco. Wall Stud Magnetic Detector uses your device’s compass (magnetometer) sensor to precisely pinpoint metal studs, nails, screws, and other metal fasteners embedded in all wooden wall studs. This app operates in a similar manner to other hand-held stud detector tools: as you move the device along the wall, the needle will move and a beep can be heard. The compass sensor detects subtle changes in the background magnetic fields caused by the conductive metal fasteners that are located in all wooden studs. Available for free on the AppStore with in-app purchases.
