Been using Nail Polish Rack for a couple months now. It’s basically an app that lets you catalog all your nail polishes – keeps track of what you have, what you’ve worn, and even lets you upload pics of the colors. Pretty solid app if you’re into beauty and nail stuff.
Here’s what you do: you can scan your polish collection and it’ll build a database for you. There’s also a feature where you can see what polishes you already own when you’re browsing the huge polish database. And you can add personal notes to each polish – took me a while to figure that out but it’s useful.
Look, if you’re into organizing your nail polish collection, you’ll probably like this. It’s not perfect – the interface can be a little clunky at times – but overall it does the job. Worth checking out.
