Electronic Toolbox Pro

I use this almost every day while revising circuits and figuring out suitable component substitutions

Work on my iPad better with mouse and key pad Thanks Dave

I don’t think anyone has a better app. Truly amazing!

I bought this app several years ago and have used it off and on. Each time I’ve launched it I was informed that the app had been updated—which of course was a pleasant occurrence. The information contained therein has always been accurate and, while it don’t use it everyday, I have no plans to ever “not have it on my phone”. I recommend this app to anyone considering it.

Helped me out many times. Hard to remember all aspects of electrical engineering and this app is ready with information.

Hoping for an update. The equation still vanishes after the answer appears on the right side of the screen. A simple 37+63=100 but, the 37+63 disappears.

This app is amazing for electronics. So many resources and features stuffed in this thing.

Great App for anyone interested in electronics.

Ive had this app for about a month or so. What I originally got this app for was drawing out schematic just basic stuff but this app has so much information and knowledge behind it. I have only begun to scratch the surface on its capabilities. I would say I’m a novice to mid level when it comes to electronics more of a hobbyist but this app has pushed me to learn more outside of my day to day applications. This is well worth the money so many good tools and information.

The circuit editor is non-functional with touch input, and the app is virtually useless on the iPhone. I fought $7 of digital garbage. No auto save, you just lose work, whole files disappear. App constantly crashes.
