Engineer smartphone apps

A smartphone is an amazing gadget for anyone to have. But for engineers, it can be a lifesaver when it comes to its computing power and mobility. Here are 10 apps that every engineer should have in his or her smartphone.

1. Touch Calc


Every engineer needs a trusty calculator. The TouchCalc has a scientific mode, bit/integer mode and a statistics mode to allow engineers to use this one app for a variety of numerical and analytical tasks. Each mode is able to perform the task that any scientific calculator can perform. The app is available for free.

2. LuxCalc Fluid Prop


Allows engineers to calculate thermophysical properties of common fluids within an accuracy of 5%. Great for thermal analysis, this app can give you data for any given temperature found in heat transfer books such as specific heat, viscosity (both absolute and dynamic), thermal expansion, etc. The app is small in size and costs only $0.99.

3. HVAC Professional


The HVAC Professional Formulator is a very thorough app. It contains 200 formulas, 18 charts and the complete International Mechanical Code. There are various sections that cover different aspects of engineering such as BTU conversions, energy values, heating requirements, heating design, loads, pumps, steam, temperature and many more. The app costs $7.99

4. AutoCAD 360 (WS)


This free app lets engineers view, edit and share DWG format drawings. This provides a portable and convenient method for managing DWG, DWF and DSXF files at any location, even on site. Files sent as email attachments can also be viewed and edited with this app. A must have for designing engineers.

5. FingerCAD


A computer-aided design (CAD) app for technical drawing purposes. Engineers can draw anything using FingerCAD that they could draw using the PC counterparts, including houses, mechanical components, bridges, geometrical figures and many more. The app costs $5.99.

6. TurboViewer X


This app allows you to view 2-D and 3-D DWG files and use multi-touch functions that allow you to zoom in, out, pan and rotate the drawings to view them at different angles. The files can be viewed by directly emailing them to your smartphone or iPad. The app costs $6.99.

7. Graphing Calculator


This app allows you to use your iPad as a function plotter and scientific calculator. The app includes a custom keyboard which allows you to type equations more quickly and conveniently and can plot multiple equations on a single graph. The graph can be viewed in real time and screenshots can be emailed easily. The Graphing Calculator costs $1.99.

8. Engineering Unit Conversion


This app can be used by engineers, scientists and students. A must have for anyone related to the field of engineering, this unit conversion app offers dimensions used by engineers on a daily basis. Simple to use, this unit converter can even handle negative values for temperature and pressure. The cost of this app is only $1.99.

9. Mechanical Engineer


This app made exclusively for mechanical engineers contains 300 mechanical engineering formulas, 300 additional conversion formulas and 70 area formulas. The app has sections including fluid power, heat transfer, internal combustion, kinetic energy, power plants, shafts springs, vehicle drive and many more. The cost of the app is $5.99.

10. Engineering Professional


This app covers all the major fields of engineering such as chemical, civil, mechanical, electrical, environmental and hydrology. Containing 650 formulas from all the combined fields and an additional 100 conversion formulas along with a section for area formulas, this app is the best all-rounder. The app costs $11.99.
