Apps for Gearheads by Gearheads
If you are a Gearhead, this is the app for you!

All of the apps work in both standard and metric units, and none of the apps have ads or require special permissions.
Easy to use Menus
Simple and easy to navigate between calculating various aspects of engine or vehicle parameters.
Illustrated Instructional Diagrams
There are diagrams in some info pages to illustrate exactly where to measure for more accurate results.
All negative signs are replaced with slider switches for less confusion and more clear description of things like piston domes/dishes, etc.
