Resister is a calculator for your electric resistors, for those moments when you have lots of resistors and you need to check the value and tolerance of them by their color, well now you don't need to check the value of every color and do the necessary math to know its value, you just need to use your Resister app.
Select the type of resistor you have (4 or 5 band resistor) and select the colors it has, then it will give you it's value and tolerance right after pressing the Ω button.
You can even change the resistor color (commonly beige or blue) just for fun.
There may be other apps that do the same this one does, but this one has a great style, feels really fluid when using it and there are lots of updates coming for this app, you can also use it in landscape or portrait orientation!
