It works... but nags you to pay – Stud Finder® Review

You get seconds to try and find a stud before it blocks you from using the app for 5-10 seconds. Good luck trying to find a stud with the limitations this “free” app gives you. This kind of practice I frown upon and in no way would support it. The app works, as it should considering I’ve used this kind of app in the past on android, (which you can find a free app that has no limit to how long you could use it) but it’s unusable as is.
