Ratings and reviews

Was a fantastic app, now I can barely navigate menus without interstitial ads, 20% of the content is covered by ads and a 15 minute trial for pro? That's just insulting. edit: Dev reply was nice and I'll certainly try it out again but the interstitials are brutal. I've got ADHD and by the time I can skip them I've already forgotten what I was going to look up.

That's good! I wish there was a premium version that i can support the creator It isn't perfect tho, you scaled some things wrongly like Arduino boards.

It is such a nice app which contains everything about electronic. Very useful to students as well as all people.
