OnFlow is an AI fitness coach built for users with deadlines for their fitness goals. Tell it your goal, "gain 4kg muscle in 23 days" or "lose 10kg by December", and it builds a personalized daily diet + workout plan, then tracks adherence. Macros anchored to real food data. Each day: get your target, log food + workouts in natural units, track progress live. Off track? OnFlow tells you why.
Hey PH 👋 I'm Keith, co-founder of OnFlow.
Most fitness apps hand you a generic plan and a calorie counter. The gap I kept hitting: they don't log real food the way you actually eat, and they never tell you why progress stalls. So we built OnFlow around one line, "Tell us your goal. We'll get you there."
You give it a real target with a date. It respects that date (no substituting its own estimate), builds diet + training around it, and every week diagnoses adherence against real nutrition-database macros, then proposes concrete swaps.
Would love feedback on the weekly-review loop. What would make you trust an AI coach over a human PT?
