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!

Thanks for a review. I hope that EE Helper will be helpful for your electronics study 🔋
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.

Blown Away!

I’m a electronics hobbyist and dabble in it at work as well. I was looking for an app for resistor color coding and noticed the high reviews for this one so downloaded it. When I started to skim the app I was completely blown away with how in depth and comprehensive it was! This is the best technical app I’ve ever come across! If you use electronics in any way, you have to download this app! I immediately went and bought the Pro version just to support the creator!

Thank you very much for the review and financial support 🙂
Excellent data all at one place

One of the finest application, which I liked it has a lot more than what I was looking for. I would highly recommend, and I would really be saying thank you to the maker of this app. This is really so good app for the enthusiast hobbies. Specially, I am a raspberry and ESP user and I loved looking every detail about the pinout and this is really helpful for me

Thank you very much for such an in-depth review of the app 🙂
In this update:
- Differential amplifier calculator. Solve for any unknown parameter (resistor values, input or output voltages) in a differential op-amp circuit. Calculates inverting and non-inverting gain.
- [PRO] Wire resistance calculator. Determine the DC resistance of a conductor based on its material, cross-section, temperature and length. Supports AWG, IEC 60228 standard sizes, and custom circular or rectangular cross-sections. Also calculates voltage drop and dissipated power.
- Pinouts for Orange Pi 4 Pro and Zero 3 single board computers.
Big thank you to everybody who subscribed or purchased the app's PRO version. Your support helps to make this app even better. If you like this app, please rate it and leave a review.
