Yepp is the social betting platform: you can challenge your friends to bet on football events (single matches or championships) on various prizes: fame, beers, crazy haircuts or even money.


Yepp has been around since 2010 as a web platform ( and later Yepp is a social betting platform that allows users
to challenge their friends on different prizes like fame, beers, crazy haircuts or even money.

In 2018 Yepp switched completely to mobile, taking full advantage of the mobile platforms: Android and iOS. The Yepp app makes it really easy for their users to challenge their friends, place bets and check out results on the go.



The Goals

  • iOS and Android apps with a playful design
  • Football matches data automatically pulled from
    a football API for European and international championships
  • User prediction score automatically calculated at
    the end of each match
  • Application and infrastructure should work for
    tens of thousands of users that create challenges with hundreds of matches

The Challenges

  • Apps need to look the same on iOS and Android
  • The design should be easy to use
  • Integration with the football API
  • Scalability: ability to create challenges with thousands of users that contain hundreds of matches

What I like most about Atta team is that they got involved in the development of the product, not just writing lines of code.


3.5 Billion Football Fans Worldwide

I won, you buy the next beer!

Matches are more fun to watch with friends. The experience of looking at matches is enhanced by the ability to make friendly bets: who leads at half-time, who leads at full-time, what is the exact score, who scores at least one goal


How We Did It

The Yepp software system is elegant and fast. We built the following software components:

  • Mobile apps implemented using React Native technology, the best solution for hybrid mobile development.
  • Backend based on Parse Server, one of the most popular back-end as a service solutions available, implemented on top of Heroku for easy scalability


  • Cost-effective implementation – with React Native, you write almost the same code for iOS and Android. Parse Server is a BaaS solution perfect for mobile apps, accelerating development time.
  • Easy maintenance – because with React Native you write the same code for iOS and Android, you have to maintain less code.
  • React Native – Yepp joins big apps worldwide that use the same technology for their mobile apps: Facebook, Instagram, Airbnb, Bloomberg, Uber Eats, etc.
  • Almost instant scalability – Parse Server on top of Heroku allows to scale up/scale down the infrastructure when needed.
  • Flexible development – with React Native, you can always implement components natively for iOS and/or Android.
