I used Matt's app during my rehab and I believe it is a great tool to understand how arm strain works. It helped me build out a plan to stay healthy. I would recommend the app for anyone who wants to learn more about how to stay healthy and learn exercises to do so.

Common questions
Before you sign up.
Is there really a credit card required for the trial?
Yes. You add a card at sign-up so your account can roll straight into a subscription if DAL is working for you. Your card won't be charged until after your 7-day trial ends. Cancel anytime before then at no charge.
What am I charged after the trial?
The plan you picked at sign-up: $9.99/month per player on the parent plan, or $49/month for the Coach Portal. You can cancel anytime, before or after the trial converts. Email support@diamondarmlab.com and it's done.
Is my kid's data private?
Yes. DAL is COPPA-compliant by design. Accounts for players under 13 must be created and managed by a parent or legal guardian, video uploads of minors require parent-verified consent, and parents can review, correct, or delete their child's data at any time. Read the full privacy policy.
I coach a team and my own kid is on it. Which plan?
The Coach Portal covers your whole roster, up to 30 players, and includes everything in the parent plan for each of them. Your own kid counts as one of the 30, so you don't need a separate parent plan on top.
Does DAL diagnose injuries?
No. DAL tracks workload and surfaces patterns that matter. It doesn't diagnose or prescribe. DAL doesn't make decisions. It starts conversations.
What ages is DAL built for?
10 to 18. The programs, load recommendations, and recovery guidelines are calibrated for youth and high-school-age players.
Can one parent track multiple kids?
Yes. Each player is $9.99/mo, same account, separate dashboards. Siblings on the same team also show up under a coach's roster.
Does the Coach Portal include parent accounts?
Coaches can invite parents to view their own player's data. Parents see their kid. Coaches see the team.
What happens at the field with no signal?
DAL is a PWA. Install it to the home screen. Log sessions offline. It syncs automatically when you reconnect.
