Collection management

What sites or apps these days do you guys use to manage or track what you pull? What is usually accepted for price checking etc?

For all the commons or lower value cards for each colour how are you going to store and sort them in real life? Just by each colour, each colours sub category (unit, spell, gear, champ) etc

It's been 12 years since I last played a tcg so I'm sure things have changed a lot
