Diamond Atelier

Diamond Atelier is an offline baseball situation board for discussing options, not judging them.

Set up a field, place defenders, runners and a ball, then sketch possible throws and movement paths with labelled directional lines. Save named solution variants for the same situation and compare two alternatives on one consistent field view, with editable notes and an optional preferred choice.

Use it to:
• Create baseball situations from a blank board or built-in local examples
• Move and label players, runners and the ball
• Draw different line types for throws and movements
• Save drafts and named variants locally
• Compare two saved variants without scores, simulation or automatic tactical ratings
• Search your library by title or task, mark favourites and duplicate situations
• Add one optional camera photo of a paper sketch to a saved situation’s details

The app works entirely on your device. There are no network requests, accounts, cloud sync, remote data or notifications. User text stays as entered, and all core features work without camera access.
