You read the material. You felt it land. Then weeks later the memories faded. That's not a failure – it's human biology. The mind forgets what it isn't reminded of. But the best ideas deserve to stay. Yada is the memory layer for the knowledge you care about. So what you learn actually compounds. Forever. So you become someone who knows. Yada Pro is available as an auto-renewable subscription. Payment will be charged to your Apple Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. Any unused portion of a free trial is forfeited when you purchase a subscription. Subscriptions may be managed, and auto-renewal turned off, in your Account Settings after purchase.
