Has everything you could possibly need as an electronic technician or experimenter. A+
You only have to use this app once to understand how much information is now at your fingertips. And the more you use it the more you will discover how detailed it gets. Then you’ll be amazed at how often the app is updated and maintained. I have used numerous electronics apps over the years, this is the one that hasn’t been removed from my devices.
Exceptional toolbox with great content, easy to visualize the devices and select. A must for anyone from professional EE to DIYer.
This is one of the apps I use on a daily basis for electronics and electrical repair, this is not available on Samsung so I will never switch phones I can’t loose this app
The image of the page showing conponents shows vacuum tubes, but after purchasing, apparently, tubes are not available to use to construct circuits.
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.
