What's New in Version 6.0.0

The brand-new Electronics Engineering ToolKit is here! Now as a universal app for iPhone and iPad! The app has now gained something so great and amazing, I trust you will like it as much as I do. I have implemented an amazingly great multi-functional keyboard! Input of values with units, E Series, tolerances, slider ranges etc. was never easier! A multi-functional keyboard like that is really perfect for an engineering tool like the EE ToolKit! Try it yourself!

In order to make this happen I had to change a lot under the hood and implement many parts of the app from the ground up. But it was totally worth it. In addition also the conversion of units for the calculated results is now more simple and convenient than ever.

Units for calculated results are set to "Auto"-convert per default. This means, if the value of a resistor is for instance 47000Ω, the tool automatically converts it to 47kΩ. This can of course be configured completely flexible.

I have re-structured, graphically improved, enhanced the UI and on top of this, added lots of new features:

Ω support for iOS 8
Ω optimized for iPhone 6 and iPhone 6 Plus
Ω complete update of the component Color Codes:
- added color picker to the resistor, capacitor and inductor color codes.
- added 5 band capacitor tool
- greatly improved look and feel of the complete color code toolset
Ω splashscreen on/off setting
Ω global decimal point setting (previously it could be configured for every calculator individually)
Ω added 4 new tools to the basic section (serial/parallel capacitors and serial/parallel inductors)
Ω extended decibel converter tool
Ω corrected, improved and extended all Info views that provide more content and explanations on the individual tools
Ω frequency generator specific:
- extended range for frequency selection
- extended range for sweep times
- added volume sweep / frequency sweep selection
- wobble effect (sweep repeat)
- added playback for musical notes
- live waveform animation
- extended presets to 16
- live quick selection for Speaker L+R / L / R on Frequency Generator and Sweep View (previously this was accessible only on the Settings page)
- bugfix for the frequency repeatedly jumping back to 1Hz (after starting playback in case frequency min/max limits were exceeded in a previous step. E.g. having typed 22000Hz)

Please don't forget to also rate this new version of the EE ToolKit. This is very important for me. Thank you so much!
