General Engineering Free
Get rid of the advertisements by buying the General Engineering (Paid) version.This free version has STOPPED adding calculation modules. It will only fix any possible bugs.New modules are ONLY added to the paid version.
Any positive constructive critique is welcome. And if you want more modules to be added, we'll be very glad to do so. But please concentrate on important hard-to-follow formulas when calculating manually. This application is meant to ease calculations without getting lost between the variables of the engineering equation or formula.
Please write the review in either English or Arabic. The computer translation is weak.
Please read the description till the bottom. It's important.
In this application, You can send the calculation results via:
- Email (at least get Gmail client for Android installed)
- Skype (if installed)
- SMS (The usual classic mobile messaging).
- In paid version only: A log of all calculations done with a time stamp so you don't have to repeat calculating them.
The application covers the following topics:A table of units.A table of physical constants.Forward and backward conversion between units (more than 50 conversions).
From applied maths for engineers:1
- Geometry area and volume.2
- Finding the location of centroids of important shapes. 3
- Finding the roots of 2nd,3rd,4th, and 5th degree equations with complex roots too.
From electrical and electronic engineering:1
- A module for Ohm's Law . It helps you find either Power,Resistance, Intensity, or Voltage.2
- Resultant sum of either of Resistances, Capacitors, or Inductances whether they are in series or in parallel. you can have up to 10 elements (which is more than enough)3
- A module to find the change in the value of the motor resistance of the wire windings after getting some heat through runtime4
- Voltage Drop5
- Resistance value using colour codes6
- Wheatstone Bridge7
- Butterworth Tee LC Filters (High pass and Low pass)8
- Chebychev Tee LC Filters (High pass and Low pass)9
- Butterworth equal component Filters (High pass and Low pass)10
- Pi attenuator11
- T-attenuator12
- Helix Antenna Design13
- Battery life14
- BJT Transistor Bias Voltage Calculation15
- Non-inverting op-Amp resistor16
- Zener diode17
- Radar Range
From Mechanical Engineering:1
- Resultant sum of two forces acting at the same point2
- Using the altitude and the latitude given by the GPS in the phone, find the exact value of the gravitational acceleration of the earth.3
- Rectangular Beam Deflection (hollow and solid)4
- Round Beam Deflection (hollow and solid)5
- Internal screw thread shear area6
- External screw thread shear area7
- Cam-with-follower Profile determination. here you can see both the coordinates of the profile of the cam on a step of 1 degree only, and get the profile plotted so you can see how it would look like.The following are Functional ONLY in the Paid versionElect.Eng.:*
- Light Lux meterM.Eng.:*
- Shear and Shear Force *
- Cartesian Fluid Flow Analysis.*
- Beams : Moment of inertia+Section Modulus+Radius of Gyration.*
- Beams : Stress & Deflection studies.*
- Interpolation on Saturated Steam Tables*
- Heat transfer through walls.*
- Heat loss from pipes wrapped with insulators.Notice: =====The application uses GPS. It's used only in taking the coordinates for the sake of calculations. If you are in doubt that we might steal your coordinates, you can use the manual input option. You have been warned. Thanks.-*

Good app. Would like to know if you have worked on any automobile and electronics related stuff.
I never said it crashed i said ot did not wirk as it not load, trying on another device now. See if you fixed it or nor. Nothing. Dev.: I messed up my phone?, by doing what? Every other app works fine, phone is brand new android 4.0.4 ICS just out of the box, a week old. Proof? Your calling me a liar? Why would I lie?
Not able to install , tried installing several times but a error comes in the end.
I just want to try b4
Easy to learn
What this app aims to accomplish is great. Toolkits of this sort are great. Unfortunately the user interface really lets this one down. Diagrams are static and don't reflect your entered parameters. While it technically works on a tablet the UI doesn't scale and rsults in a small difficult to read display. There are much more complete and functional electronics toolkits out there, still I was looking for mechanical engineering tools so not a strong criticism. I'll check again later. Recent versions have turned into Nag-ware, uninstalling.
I tested the tool, it is great. But I would use it extreme seldom. Annoying is they ask me every day to upgrade to the paid version. I guess I'll delete it for this reason. What is here the difference between "force" & "remind" if we are "forcing reminded" every day to go to the paid version ? Don't offer it for free and leave us in peace would be my suggestion.
This is a good app for basic referral to equations you might need but the constant auto loading and the way the developers force the paid version on you makes me want to delete it.
It is good for students..
Very useful application...
I am fine with ads within the application, as obviously it's necessary, and even the toast messages telling you to buy pro version. However, the app sends a notification to the notification area telling you to buy the pro version. Functionality is there, but I won't keep it installed with such invasive advertising.
The program runs at startup - BAD. The program puts up ads so large they can't be closed-BAD. The program forces alerts on you-BAD. Uninstalled. This is not how to get intelligent people to pay for the upgrade. Failed
I find it so easy to use. I recommend your effort, but you still need to work more on it.
good application
Great app for electrical engineering students. I liked the voltage drop calculations.
its a nice app i really like it vrry much
Tried to evaluate this app but the advertising was constantly interrupting and taking over. I became too annoyed and gave up.
I was nt knowing that u r solo developer... Being solo and making such an app is really Fabulous Hats Off.... I know wt all we have to face in making a app....!!! Hope in future I can see more designs ...!!!
Nice app for every mechanical engineers.
I loved the app and what it can do but would give 5 stars if it can add more stuff like calculating centroid of irregular shapes or stuff about fluid mechanics, virtual work, impulse and other things for for basic things it was pretty good. I'll be looking forward to more things being added
At first glance looks like a good app, looks better than the rest. (In terms of capabilities) The problem starts when you want to use. All your clicking opens a huge advertisement. When that you try to close it, sends you to the store to download some game Even if I want to use it I can not. It's like watching commercials without break. As long as it this way, I do not install it again.
The update of this application will install in your phone a Widget for downloading others apps of the supplier. If you delete this widget it will appear again anytime that you restart on shut on your phone. Beside that issue, after updating the app. my phone started to "awake" ramdomly so I had to uninstall the application. Be aware!
it's useless Iam sorry for my words but I installed it and I found it has nothing could help ... I thought it has calculation or something wow but I found some words written in my note book years ago
Program was overall helpful, however it installed adware that placed an ad icon on my home screen after reboots. Uninstalled until app reverts to traditional advertising.
Dingle dingle buy pro version for 5 USD.... Hey stop such childish ways
Uninstalled it because it load itself and i hate that. No need to do this.
Sorry, but what I saw is pretty fundamental stuff and frankly paying $5 for the one thing that may have saved me a) getting my Bosch SAE book out and b) using my calculator with, erm, no thanks. And since I'm mechanical on the measurements side of R&D, bridge stuff is applied on mechanical measurements. Not that your bridge stuff is complete enough to use anyway. Good effort though.
