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 on day 8 if it's working for you. You will not be charged until day 8, and you can cancel anytime before then with no charge.
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.
