I am also engineer, that is why I have made this app not only for me but also for you!
People from aeronautics, automotive, textile industries already use it.
READ_PHONE_STATE permission is needed by Admob (Google) for displaying ads in this app but not used by me! Pro version does not need these permissions.
First start of the app may take up to 10 seconds.
The running of the app needs also Adobe Air.
Engineer Companion contains:
- periodic table of the elements. (Mendeleiev classification table) including detailled informations (atomic weight, radius, electronic configuration, crystal structure, thermodynamical properties...)
- unit converter (length, surface/area, volume, force, heat capacity, speed/velocity, time, volume flow, energy/torque,heat conductivity, acceleration, mass, mass flow, power, cinematic viscosity, angle, inertia, concentration/density, temperature, dynamic viscosity, angular velocity/frequency, molecular concentration, illuminance, pressure/stress, radiation, angular acceleration, memory, magnetic flux, fuel consumption/fuel economy/CO2 emissions, textile units, tex)
- list of most frequently used constants
- explanation of STP,NTP,SATP, normal or standard temperature and pressure conditions.
Upgrade to Pro version for:
- no ads (this means also less permissions)
- user defined units for each category
- extended definition of user units in the user defined category
- quick cross-multiplication module
Thanks to Daniel Freeman for its MadComponents
Please report new units that you would like to be integrated in the next version.
Please report errors or suggestions! Thanks.
No special scroll wheels, great dimension graphic, fast drill chart, accurate - true data from the handbooks for the thread sizes you need.

---Things you should know---
• App developer doesn't participate in the purchase and download process, if you have problems with credit card authorization, charge, double charge, download failures, we have no way to help you, you'll need to check the Google technical help forum.
• Update is always free, Google controls charging and it WILL NOT charge for update.
Quick data entry is paramount when determining what to pump on scene. Input on mobile devices can be tedious and sometimes difficult when forwarding the latest joke to your crew. Now imagine typing all the hose lengths, various flows and nozzle pressures when your at the “big one”! You can’t delay and recalling rote memorized hydraulic formulas can be difficult at 3am.
Most of the app is structured in a step-by-step fashion leading to the eventual calculated data, I.e. PDP, FL, etc. It was designed to be intuitive and easy to use. Please let me know what you would like to add, change or otherwise improve as this app is for you.
I'm rapidly developing and hope to add some seriously cool features for my brothers and sisters in the fire service across the globe. Stay connected!
Standard, built to cause the engineering menu, you need to dial *#*#3646633#*#* , which is not very convenient and practical - is a tiny application designed to eliminate this inconvenience :)
- Has a minimum size - just 25KByte.
- Does not require any permits.
- Do not "hanging" in memory.
- No advertising.
!! Application is only for devices running MTK (MediaTek). If you have a different platform, you will get a message that the device is not supported with the proposal to uninstall this applicaton.
!!! Attention. On some devices (basically, these are some models of Huawei) manufacturers denies access to the Engineering Menu, in connection with which these devices will be able to function the program only with the given Root access.
For those who would like to support the project, offer donate-version: Engineer Mode MTK donate
12/1/2013 - Added a Tap Drills for U.S. Sizes chart with drill sizes for 100%, 75%, and 50% threads as well as clearance sizes.
6/12/2014 - Added a Tap Drills for Metric Sizes chart with drill sizes for 75%, and 50% threads as well as clearance sizes. Added a welcome screen to show new features.
6/22/2014 - Added a button to upgrade to Drill Bit Charts Pro which is available for the minimum paid fee It includes a handy Unit Converter and will be getting new features like a newly added Wood Screws chart.
10/21/14 - Fixed a theme issue on some new devices with previews of Lollipop.
Please feel free to rate, review, and comment on the app. It will continue to get enhancements and new features. Please tell your friends and colleagues about it.
This app is part of my RC Calculators paid app for R/C modelers. I broke it out into a separate app because I found it very useful and wanted to make the drill charts free. There is now a version called RC Calculators Free Edition. It has a Unit Converter, Engine size calculator, Battery Voltage calculator, and other tools that even non-modelers will find useful.
Designed to Create, Manage and Accelerate your Business.

This app gives drill and tap tables for all common thread sizes including: United National Coarse, United National Fine, National Pipe Tapered, National Pipe Straight, Metric Coarse, and Metric Fine. The drill and tap tables show drill letters and decimal values.
*ANSI Drill Size Table
*Inch - Millimeter Conversion Tool
*Clearance Hole Tables
*Light and Dark Themes
✔ Database Search - used to search for pipe properties and dimensions (ASME B36.10); pipe fittings, like elbows, tees and crosses, up to 36" (ASME B36.9); and flanges, which include blind, slip on, threaded, welded neck, socket welding and lapped (ASME B16.5).
✔ Pipe Thickness - used to find the pipe thickness needed to withstand the inner pressure (based on ASME B31.1 and ASME B31.4).
✔ Pipe Diameter - used to calculate the pipe diameter needed to carry the fluid with the designed flow, this module uses the pressure loss equations to find the diameter.
✔ Project Management - a module that store all the results from calculations generated by the modules. It can also generate a pdf file report of your projects.
✔ Unit Converter module are also being developed.
✔ Calculator with built-in piping equations and database.
✔ 45° Pipe Cross - used to calculate the linear distance between pipes when one cross another using a 45° Elbow.
✔ Support Spacing - module that calculate the maximum span between the piping supports.
✔ Pump Power - calculate the power needed by the pump and the shaft power delivered by it.
✔ Stress Analysis - this module comes in three sub-modules: stress analysis in "L" pipeline system, in "U" pipeline system and "Z" pipeline system. Maybe there'll be a forth one, as I'm developing a module that will use the finite element method (FEM) to calculate the stresses.
✔ Pressure Vessel - this module have two sub-modules: pressure vessel head (calculate the following types of head: ellipsoidal, hemispherical, torispherical, conical and toriconical) and pressure vessel shell (calculate the following types of shell: cylindrical and spherical), both calculated using ASME Section VIII Division I.
✔ Bolt Torque calculation for flanged connections, based in the ASME PCC-1 standard code.
This app uses both SI (International Unit System) and US (United States Unit Systm, or Imperial Unit System).
A user can also achieve torque and horsepower recommendations based on the type and size of tap, material being tapped, spindle RPM and tap style used (hand, spiral point, spiral flute).
Tap application calculations are further enhanced by a fully functional trigonometry calculator which aids in resolving angles in certain tapping applications. Practical tapping applications include determining hole positions and calculating the material depth required to drill a hole at any angle.
Drill provides a simple, easy to use interface that replaces tedious hand written set books/dot books/drill books.
- Excellent visualization of sets on the field
- Easily store notes for each set
- College and high school hashes
- View the paths connecting the previous and next sets of the selected set
- Shows mid and quarter points
- Zoom through the field to get a closer view of sets
- Supports specially named sets e.g. 1, 2a, 2b, 2c, 3, etc
- Looks great on tablets
Drill is the ultimate solution to the marching band or drum corps member.
For free, it eliminates the need to carry a burdensome notebook/binder around, and adds the features to allow you to better learn your sets.
Simple tap and drill chart with nut sizes and clearance holes. Metric and US inch SAE. Shows screw/bolt size, clearance holes, tap drills and nut sizes/hex head size width across flats.
Requires no permissions. If you find this app useful, please leave a review. It is knowing that people use and love my apps that keeps us totally free and non-spyware app developers motivated.
