Not influencers. Not sponsored athletes. People who downloaded the app and kept showing up.
I've tried six fitness apps. FitAI is the first one that actually noticed I was burning out before I did. It dropped my intensity for a week and I hit a PR the following Monday.

“The nutrition AI is what separates this from everything else. It doesn't give me a meal plan — it adjusts my macros based on what I did that day. That's actually smart.”
