Easy to use, Awesome, Well designed!!!

I have used many helper apps before, none have ever had this depth, precision, and though that was put into this one. While not only visually well thought out, the tools are sorted into logical categories that make them easy to find. The best part is that the pro features are not the core features of the app like they are in many other apps, for once I have an app the is helpful and functional without being stuck behind a paywall! While I have yet to get the pro features, they only add to the apps usefulness, rather than detracting for its core functionality like every other app for this purpose I have ever used. I am also impressed with the software. There are no hidden bugs! Nothing that you get stuck on, that takes a few tries, or that otherwise wastes your time. This app works well reliably and has saved me so much time and headache. I would recommend it to any electrical engineer out there looking for a helper.

Everything you need to get started!

This app is amazing! It has absolutely everything you could possibly need as a beginner to Electronics. I haven’t noticed any problems with it. And nothing is locked! With other apps, some of the features have a lock buy them telling you to get the full version. With this app you don’t feel like you’re getting left out on everything because they just don’t show you everything you can’t use. Get this app!

Education

I’m an older guy 60 plus years old . This a world of information. I’m actually just a maintenance guy at a college. I share this app with several engineering students. They flipped out when they found this app.. Really you people did you’re home work . Thanks for sharing this app and information

Developer Response ,

Thank you very much for such a great feedback. I'm glad that this app helps you 🙂
