Awesome app

Awesome app

Sehr gut

Tolles Programm, sehr nützlich. Schön wäre es wenn es ebenfalls auf dem Mac laufen würde.

Swiss Army knife for electronic engineers and hobbyists

The app is practical, portable, affordable and most importantly, recommendable.

It’s easy to use, continually updated and saves countless time hunting for that missing formula. It’s a go to app for hobbyists and professionals alike.

Thank you Marcus for sticking at it.

Just bought this

Just got this App, and again I am amazed at how much work and effort this developer puts into his app.
I tried at one time making my own app, and although I was able to do simple apps, I gave up when trying to do more detailed and complicated app so I know a lot of work goes into it. One of the great features about all his apps is “none of that subscription garbage which other greedy money hungry developers push”, subscription is rubbish and makes no sense.
I have decided to compete with this developer and make a similar item to give him a run for his money, but I would strongly advise everyone to stick to his apps, unless you want to buy my useless app, 😂

What a wonderful toolbox!

I’ve just opened a color tool and enjoyed a wavelength slider with a 0.1 step! Thank you!
