Engineering Calculators-Tools for Android
It looks like the bugs reported by other reviewers have been fixed.
Splash screen is displayed for to long
The decimal point is missing from the data entry keypad. How does one enter a V(BE) of less than 1 volt or a Collector resistor of say 4k7 ohms without a decimal point? Takes an awful long time to get past the splash screen and to the point of being able to do something. It is an interesting concept, but I think the implementation could use quite a bit of clean-up to improve the flow and "apparent" accuracy of the results. For example, in the dBm, dBW, Power converter, you can enter one of the terms and have it compute the other two. Except you could randomly enter all three values, NOT have it compute anything, and have a display that is is incorrect but has no indication to that fact. Or, you could enter a value and do the calculation and then change one of them (planning to do a calculation) and not hit the convert key and have an incorrect display. Awful lot of white (wasted) space on the display -- very bad when you're talking about a pocket sized device. Data fields are screen wide but only the left 1/4 of them is used. you get 3 or 4 lines of stuff crammed on the left causing fields to scroll off the screen while all this other space is unused.
Color code gives strange results.
This app contains nearly all of the calculators that an electrical hobbyist needs. The user interface isn't quite as user friendly as I would like.
Very helpful and easy to use. If you're an engineer, I highly recommend this app.

Marginally useful. You MUST put a '0' before fractional values or they're ignored (e.g. '0.7' not '.7') without explanation. This is basically a way to get their name in front of your eyes and little else.
