What's New in Diamond Nine Athletics

1.9

October 18, 2026

Version 1.9 makes joining a team simpler and safer, imports more accurate, and the app faster to open. JOINING A TEAM Athletes now join their coach with an invite code when they create an account, and coaches join their organization with a code from the admin. A coach sees only their own athletes, and athletes see only their own information. SAFETY AND PRIVACY • Report or block anyone you message from the three-dot button in a conversation. • Deleting your account now also removes your uploaded film and files. • Updated Terms and Privacy Policy. Your film is used only to run the app unless you or a parent give written permission. MORE ACCURATE IMPORTS • A session now keeps the date it was actually thrown. Imports were landing a day early. • A file with several bullpens now imports as several bullpens, each with its own date and numbers. • Files with unusual column headers no longer read velocity from the wrong column. FASTER AND CLEARER • The app opens faster. It no longer downloads every pitch at launch and loads an athlete's pitch detail when you open them. • Charts no longer make ordinary ups and downs look like a collapse. • Compare Film tells you when a clip can't play. • Cancelling a report export no longer shows an error, and "Exported" only appears when the export finished. • Roster rows, session cards and video controls now work with a keyboard and VoiceOver.
