An assessment-driven AI fitness and lifestyle coach — voice and text coaching, five languages, and subscription tiers — that tailors guidance to each user instead of serving the same generic plan.
A coaching product only works if it feels personal. That means starting from a real assessment, adapting to each user, and meeting them how they prefer to interact — by voice or by text, in their own language. On top of that, it needed a subscription model with tiers, all wrapped in an experience smooth enough that people keep coming back.
