Diamond Ledger

Diamond Ledger is a simple offline diary for friendly baseball practices. It helps manually record where, by observation, a hit ball landed, what kind of contact it had, and then display the distribution of saved records.

In the app, you can create a practice, choose a zone on a stylized baseball field, mark the contact type for balls in play, and save the record. For the foul area, the record is saved as Foul without a required contact category. Zones are categorical observations, not exact coordinates or distance measurements.

Main features:
• create and edit practices with a name, date, and note
• manually select zones in the infield, outfield, and foul area
• contact types Ground ball, Line drive, and Fly ball for balls in play
• list of saved hits with filtering by zone and contact
• edit, delete, and undo changes where offered
• overview of distribution by zone, including a separate foul count
• search and sort practices in the diary
• optionally attach one photo of the field as a visual note for a practice
• show the introduction again and set delete confirmation for individual records

Diamond Ledger does not perform automatic hit recognition, measure real coordinates or distances, keep competitive score, or provide technical recommendations. Summaries are based only on saved manual records.

The app works fully locally. It does not require an account, use network calls, remote data, or analytics services. Practices, hits, settings, and the introduction status are stored on the device.
