About this app

Quack is an app that changes the way you interact with the people around you. Once daily and at a random time, the app makes the sound of a duck. It can go off at the gym, on your way to class, or in the bathroom - you never know when!

But there's a twist: The daily quack plays at the same time for everyone who has the app installed. So if you hear a flock of ducks, it's almost certain that someone near you also has the app.

Once the quack goes off, you'll have 60 seconds to confirm that you have heard it by tapping on a notification. Make it on time and you will earn points that you can spend on accessories for your duck.

It's a fun little app that says what it does on the tin. My favorite part is when it goes off when you're out with friends or in public, the confused looks you see are priceless! My only suggestion to improve the app is to add more stuff to the shop, I know it's secondary to the main purpose of the thing but it'd be fun to see new accessories show up in there that I can decorate my duck with.

Very fun. Maybe you could add something to show how many users confirmed the quack when it passes? Also, more cosmetics when?

I love this app. We need more outfits though. Hate Christmas, refuse to buy Christmas outfits with my quack coins. Give me other outfits.
