Cal AI vs Vitalume
Cal AI made photo logging mainstream, and for a quick estimate it is delightful. It stops there: no verified database behind the guess, no training, no recovery, and a coach that does not know your history. Vitalume gives you the same one-snap logging, then closes the loop with training, readiness and a coach that explains why.
