"BadmintonManager" is a badminton match pairing and participant management app.
It's a convenient tool that allows you to quickly and easily create match pairings and manage participants all in one place.

1. Designed for thorough ease of use
This app is designed for simple and intuitive operation. Not only can you register and edit members, but you can also select participants with just one tap. It's designed to be easy to use, even for beginners, significantly reducing tedious preparation time.

2. Register up to 50 members and create pairings for up to 25 people
Supports a wide range of groups, from teams, clubs, and friend groups. Register up to 50 members and automatically generate pairings for up to 25 participants from those members. It's a safe and reliable tool for large practice sessions.

3. Quick function allows for easy pairing creation using only numbers
Don't worry if you're busy or can't register participant information right away. Simply specify the number of participants and the number of courts to automatically generate consecutive numbers starting from 1, and use them to instantly create fair and efficient match pairings.
Even if you can't register members in time, you can quickly schedule matches using only their numbers, making it extremely convenient for last-minute preparations for practice sessions or tournaments.

- Participant numbers can be used instead of names, eliminating the need for registration and editing.
- Automatically adjusts the optimal number of matches and pairings based on the number of courts.
- Flexible handling of participant substitutions and last-minute changes.

This feature makes it easy for anyone to prepare for a match and make the most of their fun badminton time.

4. Automatically Generates Fair Pairings
This feature automatically generates participant pairs and match pairings, and features an algorithm that distributes break time as evenly as possible. This prevents pairing imbalances and repeated matches against the same opponents, ensuring a smooth match progression.

5. Flexible Adaptation Based on the Number of Courts
Automatically adjusts the optimal number of matches based on the number of courts used. Supports one to four courts, allowing you to create an efficient match schedule based on court availability.

6. Easy Participant Management
Toggle member participation/non-participation with a single tap. Real-time participant status management makes it easy to handle sudden changes in participation. It's also convenient to unsubscribe in bulk.

7. Team Management
Up to three teams can be registered, each with different members. Supporting multiple groups and organizations, it prevents management confusion.

8. Convenient Save Function
Member information and match results are automatically saved. Data is retained even when the app is closed and immediately available the next time it's launched.
