Ballie is a free iPhone app developed by TSQ that aims to simplify team management for amateur sports teams in the Netherlands. With Ballie, users can easily keep track of which teammates are attending matches and training sessions. The app sends reminders to those who haven't confirmed their availability a few days before an event. Additionally, team administrators can send notifications to their teammates effortlessly.

One of the standout features of Ballie is its ability to automatically load match schedules and easily plan weekly training programs with just one click. The app is designed to provide a convenient and user-friendly experience for amateur teams, helping them overcome the weekly challenge of determining who will be present at each event.

Ballie was born out of the developers' own frustrations and the feedback they received from other amateur teams. They recognized the need for a simple and organized app that could address the common issue of team attendance. As a result, Ballie was created to provide a clear overview and allow everyone to indicate their availability.

The app is completely free to use, and the developers are eager to receive feedback on how to improve it. They are committed to continuously optimizing and enhancing Ballie, driven by their enthusiasm for the app and their desire to meet the needs of amateur sports teams.
