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.

BUILD PROGRAMS, NOT SPREADSHEETS Assign a whole training program to any number of athletes at once — pick the program, tick the athletes, set a start date. It used to mean opening each athlete one at a time. Save groups of athletes you program together and assign to them by name. The program editor now works one day at a time, with drill counts on every week and day, drag-to-reorder, and "Copy from" to pull Monday's session into Wednesday and Friday. A ROSTER THAT TELLS YOU WHO NEEDS YOU Athletes are listed A–Z with peak velo and trend on every card, and a coloured dot showing who hasn't thrown in a while. Sort by last session, quietest, peak velo or gain. Search by name, email or program. Alerts that used to repeat once per athlete are grouped into a single line. FILM YOU CAN ACTUALLY STUDY Compare two clips side by side, drag the timeline to any frame, play at half speed, and step frame by frame. Link the two clips once you've lined them up and they scrub together. The video library now shows real thumbnails, and coaches can keep their own videos alongside the Diamond Nine ones — visible only to them and their athletes. REPORTS WORTH SENDING The development report is a proper PDF: pitch arsenal, movement and release charts, progression and session log. Export it for any athlete from the dashboard. FOR ATHLETES A rebuilt profile with your headline number up top. One film screen for your session clips, your coach's videos and the drill library. Training shows today's work first and tracks the weight you lifted over time. Plyo throws now read as a ladder — best velo for each ball, heaviest to lightest. UNDER THE HOOD Saves no longer get lost on a bad connection — they queue and send when you're back. A coach and an athlete editing at the same time can't overwrite each other any more. Push notifications now reach your device. The app is smaller and opens faster. The Rankings tab has been removed so the app stays a development tool rather than a leaderboard.

New in this update: • Film Analysis — draw right on any clip. Pause on a frame and mark it up with a pen, straight lines, or the angle tool to break down mechanics, then step frame-by-frame or slow it down. • Fixed password reset — the reset code from your email now works reliably. • Fixed missing pitches — every pitch in a session (including Fastballs) now shows up in the session view, not just in your totals. • Compare Film now fills the screen — both clips play in two full, stacked boxes, easy to see side by side. • Additional fixes and improvements. Thanks for training with Diamond Nine!

This update makes Diamond Nine faster, cleaner, and more reliable: • Notifications — get a lock-screen alert when your coach posts a new session, assigns training, or you set a new PR. • My Film — every clip your coach shares with you, session film and video, now lives in one place for quick access. • Rock-solid data — your sessions, plyo numbers, and notes stay put and now flow everywhere they should: trends, over-time charts, and your Arsenal all reflect every upload. • Profile photos — tap your picture to add or change it. • A cleaner look — refreshed charts, an accurate 18-inch strike zone, an easier-to-read pitch-by-pitch view, a new app icon, and a smoother feel throughout. • New here? A quick welcome tour shows you where everything is. Thanks for training with Diamond Nine!

This update makes Diamond Nine more reliable than ever: • Rock-solid data — your plyo numbers, session videos, and notes now save permanently and will never disappear. • Smoother saving — changes save instantly and reliably, with no flicker or lost edits. • Clearer passwords — sign-up and password reset now show exactly what's required, with a live checklist as you type. • Various bug fixes and performance improvements. Thanks for being part of Diamond Nine Athletics!

Reliability fixes: coach entries (plyo velos, training plans, session notes and video) now save reliably and confirm before finishing, so nothing gets lost on a weak connection.

Plyo tab upgrades: • Progress charts — track velo trends over time by throw type and ball weight • Bulk logging — record a whole plyo session at once instead of one throw at a time • PR alerts — athletes and coaches get notified when a new personal best is set Progression chart now shows a velocity trend line with a next-month projection. Compare Film is now full-screen with synced Play/Pause, so you can watch two deliveries side-by-side at full size. Plus reliability improvements.

Coaches can now attach video and notes to any session — record or upload film and it shows up right alongside that session's data for the athlete. New Plyo tab: log plyo-ball velocities by throw type and ball weight, with best-velo tracking for each. Book a Lesson: athletes can now buy training packages and schedule sessions right from the app. Plus smarter CSV uploads that catch duplicate files, cleaner drill organization, and a range of reliability and performance improvements.

Coaches: build reusable multi-week training programs from scratch, add multiple drills at once, and extend a program across a whole season in one tap. Drills are now organized by category so variants stay together. Smarter CSV uploads that catch duplicate files, fastball-based session stats, cleaner alerts when an athlete's plan is running out, plus reliability and layout fixes.
