About this app

Zero-One is an application that helps its users to instantly and easily express their opinions about goods and services provided by businesses, and get personalized perks, gifts and discounts in return.

Oftentimes you really, really want to immediately react to something or to somebody’s actions - be it some interaction with a business or a service, behaviour of a friend or of a complete stranger - by saying something you cannot or would not do openly, because you believe it is impolite, inappropriate, or you just being afraid to offend.

With Zero-One, you can easily let your thoughts out with a mere fingertap on your phone screen.

It is totally easy. Tap “1” to upvote, or “0” to downvote. Do it openly or anonymously. You can even add a text note to explain why. Similarly, other zero-oners can let you know what they think about your actions, to help you improve your business or your behavior.

The possibilities are only limited by your imagination. But here some typical use cases that one can immediately try:

An amazing pizza at Giovanni’s:
“1” to the chefs, along with a note “Thank you, your veggie pizza was amazing!”

Can’t find your favorite sort of a candy bar?
“0” it is, along with a note “2nd time this month Dark Choco bars are out of stock.”

Getting cold from a chilly AC breeze in your local coffee shop?
“0” for that, with the side note “Too cold in here, turn up the temperature!”

Fellow rider on the train offered his seat to a senior:
“1” to him!

Two persons at the next table at your Starbucks converse loudly:
“0” to you folks, next time think of others around you.

Your colleague gave you a lift from work:
“1” to you, bud, thanks!

Your boss keeps saying something that really annoys you:
“0” to the chief, and not just from me, probably.

…and so on and on!

All these Ones and Zeroes, with attached optional notes, show everyone what and who they really are. Meanwhile an advanced algorithm runs in the background. For businesses it calculates and helps track their ratings, and get more visibility on the provided services, and for people it shows their Karma Score and compares it to scores of their friends. All shared opinions are calculated to add up to collected points that are converted into personalized perks, gifts and discounts for you, provided by many participating businesses.

Zero-One is the best and simplest way to freely express your opinion and receive perks for speaking out. It is also a great way of knowing what others really think of your actions. Don’t hesitate, download this free app and try it now!
