8 of 25I don’t think anyone has a better app.<br/>Truly amazing!
An excellent quick reference for field work or in classroom calculations. Repairing something or designing gadgets for fun from miscellaneous parts can be addictive when the answers are at your fingertips. The RF App is also handy when designing wireless antennas for exact frequencies.
The image of the page showing conponents shows vacuum tubes, but after purchasing, apparently, tubes are not available to use to construct circuits.
Great App for anyone interested in electronics.
I downloaded this app as electronics student in 2010! Thirteen years later it is still my first resource for anything electronics, and the continued updates and support make the app far more valuable than the price point. Marcus has created the Wolfram Alpha of board-level electronics!
This is the first app I install on a new phone. I’ve been using this app for many years and it’s one of the only reasons I keep a smart phone.
This is the best App you will find for electronics and general electrical data. The creator keeps it updated and continues supporting it. It just keeps improving and growing. Extremely devoted to making it better and better. I have a lot of apps where the builder makes it and moves on leaving it to be static never getting any better. I have had this one through 4 iPhones and again just keeps getting better. <br/>Thank you!!!
Very handy, I print saved page images for reference where iPhone is not safe at hand. Great fast reference to specific items<br/><br/>I may have suggestions but not for now. Thanks for efforts
