Engineers, like many people, love to be offered something that makes their life easier. Because let's face it, our profession is not always easy. As much as we love and revel in our work and no matter how good we are we can always use a little support. After all who does not?


These engineering apps provide just that and are sure to help you spend your valuable time on more important things - like sleeping and eating. 

From providing a quick reference, to useful equations to quickly and easily convert between different units, these 17 have something to offer for everyone. 

We hope you enjoy this wonderful selection and that it helps to make your engineering life a little smoother and more fun.

The following list is far from exhaustive and is in no particular order.
