Hello!
I’m just an amateur badminton player, and making app is one of my hobbies.
Playing badminton, many players often forget their positions or scores, bringing about arguments in the long run. That’s why I've decided to make this badminton score board app.
If you have experiences like this, why don’t you try this app?
I'd like to particularly extend my gratitude to Mr LEE, a member of the badminton club, who makes trouble with scores and positions every match.
