Biomed-Ted
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.
