A Phone App

Hello!
Today's topic are phone apps.  I use many of them, pinterest when I want to save an idea for later, Yummly for recipes, Duolingo for when I'm bored. 
But mostly I like useful apps that help your organize certain things or aspects of your life.
I like money tracker apps, to know how much you're spending and what for. I personally use Monefy, I wanted something simple, and wanted one where I could change the currency without having to pay for the upgrade of the app. 
There are some other apps that invented new ways to avoid repetitive tasks, or to help you find someone to do them for you, when you do not have time or the tools to do them yourself, such as uber and cornershop, I think cornershop is one of my favourites. As I don't have a car, and sometimes have to buy groceries for the whole month, it comes in handy. They also bring your things in reusable bag, which is great, as they are starting to ban plastic ones here in Chile.
