Iphone 4s so sick

First off im not some developer trying to get people to get there app. This is freaking free and it works so well i was so amazed by this thing its so precise compared to the other ones. It actually works for many many metals but some dont. It also gets affected by electronics so i dont think it detects the metals but the fields emitted from it anyways its pretty sick and does pick up metals like wires in the wall(put it on max sensitivity and do it slowly cuz its sensitive) and cordless phones or other things that can mess with the compass. If u dont believe me what it actually does is use the compass and when it gets messed up it reads it.
