The purpose of this app is to help tradesmen and do-it-yourself (DIY) enthusiasts to recognize and name most of the common (and not-so-common) types of screw heads and drivers that you might have to deal with.
The app provides a silhouette of each screw head type together with its name and summary information about its history and usage in particular products and/or industries.
For example, if you are frequently striping the heads of Phillips-head screws it's probably because it isn't a Phillips head at all: it might be a Pozidriv or a Frearson and you are using the wrong type of screwdriver - they all look very similar at first glance but this app will help you to tell them apart.
