Awesome app! I was able to detect a few nails behind my dry wall to figure out approximately where my stud is. This is the kind of app I love finding in the Play Store, it makes great use out of the limited hardware we have on our phones. Since it is dependent on the phone's hardware, I wish people would stop rating the app so low if their phones don't have a magnetic sensor. Also, It's a phone app so it shouldn't be compared to the accuracy of a $100 stud finder.
It actually works! I mean it's impossible to get an accurate results, but it gives you a general idea of where the studs are based on the small spikes in the magnetic reading from the nails. It works enough to make the job easier. This is from a Samsung S3 mini so I imagine most new phones will give as good if not a better reading. The trick is to make sure you are not wearing or near anything which will give off a magnetic reading and then move the phone slowly over the wall, looking for small, regular spikes in the reading.
Cool idea but... Since it uses the phone mag censor, the app relies on the hardware. I have an app that looks at raw hardware data. I see how it would work but on my Samsung s4, not so well. Still not sure how wood studs can effect a mag sensor. They are non ferrous. You might pick up on a screw. I bet metal studs would work great.
Very nice app!!! Tried measuring 16in apart to find stud didn't work. Didn't know how I was gonna help a friend hang a door on the wall as a headboard without a stud finder, until I found this app! Come to find out my studs were 24in apart with this app... If every review you get isn't 5 stars trust me it's not the app... upgrade your phone people!!! Worked like a charm! Thx!!!

Better than Nothing While not technically a "stud" finder per say, it does work by using a metal detector (upper left on S4) to find the nails in the studs, which is a little trickier, but it works in the end.
Awesome App Don't know if it's been mentioned before: Make sure you are not wearing a watch and/or wedding band or the like. Took me about 4 minutes to realize: Why phone kept vibrating while following steps on Youtube video. Doh!
v1.03: change vibrating pattern
v1.02: fix issue in tablet
v1.01: bug fix
v0.91: update user feedback form
v0.9: add seek bar, add default ref
v0.8: various improvements, add ad
v0.65: Add back requirements for gps and Wifi location. v0.6 removes those requirements by using geocoder service. However, geocoder service does not work well. Also modify location service and help.
v0.6: Drop requirements for gps and Wifi location. Add user feedback form. Help information improvement.
Use compass, get magnetic variation, record mag data and be a citizen scientist!
