KroegApp Unitas S.G.

Digital wallets mobile application for student association.

KroegApp Unitas S.G.

Project Overview

Unitas S.G. is a student association in Groningen with an active bar where members buy drinks every week. For years, consumptions were registered in the syste and paid later via a SEPA incasso. This system was not feasible anymore.

We built the KroegApp, a complete top-up ecosystem: a mobile wallet app for members, an iPad Point-of-Sale app behind the bar, and a web dashboard for the Board. Members top up their balance in advance and bartenders can register sales on their account. The Board gets full control and visibility over products, prices and transactions.

The Challenge

  • Paying for consumptions afterwards was no longer feasible
  • Outstanding balances were hard to track and collect
  • A prepaid top-up system was needed without adding friction for members
  • Bar staff needed a fast, reliable checkout during busy nights
  • The Board needed transparent oversight of sales and transactions

Our Solution

Member App
A React Native app on the App Store and Google Play where members top up their balance and view their transaction. Additionally, a leaderboard was added, a long-forgotten tradition of the association.
Point of Sale
A dedicated iPadOS app, also built in React Native, running on iPads behind the bar for fast checkout.
Board Dashboard
A Next.js dashboard for managing product categories, products, price tiers and users, and for viewing and auditing transactions.
Backend & Infrastructure
A Django backend that powers all three clients, with the backend and dashboard hosted on AWS.
