Leave the guess work out of working with resistors!

This simple application focuses on graphics, what you see as your work on your projects. No messing around with numbers, and no mental math... Just swipe in what you see and the resistor's resistance value is calculated before your very eyes!

Leave the guess work out of circuits!

Works for resistors in the E6, E12, E24, E48, E96, and E192 Standard EIA value system.

Basic Features:

Additional Upgrade Features: (in-App purchase)

Upgrade Features

About the comment "Ok but not as pictured...", its true you cannot enter a numeric value as pictured. This is because that is one of the Upgrade features available after the in-app upgrade purchase.

There are other features that are also available once you upgrade, as noted in the App Description and in the first two images.

Can't restore purchase!

Good app while it's working but I deleted it to free up space and re-downloaded it. Now when I try to activate the pro features I already paid for(!) the app freezes and won't wake up until I force quit it. I can't use the app now because the features I purchased are essential to my projects. Please update with a fix for restoring purchases!!

Can't restore.

I like the app. But I cannot restore it on my new iPhone from my cloud. It shows it downloaded but when I go to open it,it closes out right away. Plz fix this bug!!!
