Non pagare *2021-12-20, version 3.9* Viene fatta passare per un calcolatore di circuiti, ma non lo è! 3€ buttati! ### 3/5 — English Ha Ha Ha *2021-06-06* Whatever language this was originally written in the translation to ‘English’ is hilarious. I paid for the ‘Pro’ version just to remove the ads. It’s a shocking App in all fairness because of what’s ‘lost in translation’. I had a go at the quizzes and I was scratching my head thinking what the flip are they on about? Not because of my ineptitude in electronics (I have qualifications in Electrical Engineering & Electronic Engineering; I also have over 30yrs of practical experience in the field) Give the free version a go but don’t expect much in the way of being educated. It was only £3 and I get to have a laugh every time I read it 🤣 ## Frequently asked questions about ElectroMaster Pro ### What electro-technical topics does ElectroMaster Pro cover?
