eTools PRO App Reviews

Very helpful! And the interface is easy to use.

Really useful and informative

Every page of this app is well thought out with its design. The calculators make it easy to enter the information with diagrams showing the calculation. There are pinout diagrams of just about every connector you will run into today. The reference sections tie a lot of different information into a concise one-stop-shop for just about anything electrical or electronic. What prompted this review? The developers quick, polite response to a feature request and it being there in the next release.

Plus for them!

Use it often as a computer tech. Great tool and a must have IMO.

Very nice and handy tool for IPhone and IPad! If you are working with electronics and want to have all basics by hand..then there is no reason to look further...Like the PDF links, hope the developer will also a quick email and a print page button on the pages...Super!

This is an invaluable resource for electronics, electrical, and biomedical engineering students and professionals Its great as both a study tool as well as a quick lab / field reference. I started with the free app and loved it so much, I got the pro version and the added content was well worth the price. I wish it had a built in scientific / engineering calculator, formula quick reference, and periodic table. Would buy it again in a heartbeat.

I use this almost everyday been a tech for 35 years and love the app WELL DONE
