It is really helpful but take time to understand but only for electrical people
★★★★★Haruni Msofe· Jun 26, 2021
Great app im a beginner to electronica alliance and now im benefiting with it
★★★★★Igwe Victor· Apr 25, 2023
It's really good for Beginners and professionals in Electronics Engineering
★★★★★Edwin G Gill· Mar 21, 2022
Working with HP 54615B oscilloscope 500mhz, really helps, thank you, with all these small micro / nano parts, .and adding a needle to the soldering iron. Makes it better for me, with all the information .im able to re-design apply. Junk parts into good use.

Very good app and good explanation on how between component work
★★★★★Fitsum· Apr 26, 2024
I am electronics engineer Very interesting thank you very much

Stupid app. Only has a 4 stripe resistor and I have a 5 stripe

Full screen video ads. Video ads pay more than banner ads. Thank God the ads I have seen in the short 30 seconds I used the app for were a few seconds. There is no reason to choose to have video ads in an app that doesn't play video. It's out of place and extremely unwanted. No option to disable ads. In an environment that this app would be needed, blaring sounds and disabling app usage is unacceptable. The extra star because it's not the worst ad delivery app.

I was thinking of paying for pro but after seeing how many tracking attempts this app try to get my personal information I'm just going to delete it. Teaming up with a company that has enough of our personal information is pretty low. We can't do anything without someone trying to get something out of us. Well you can have your team google app back.
