FitFlowGPT

Flow smarter. Train better.

Inspiration

I wanted to make fitness accessible and personal — not everyone can afford a trainer, but everyone deserves a plan that fits their body and goals. FitFlow GPT was born from the idea that AI can be your pocket fitness coach.

What it does

FitFlow GPT is a 3-in-1 fitness app: it delivers daily AI-generated motivational quotes, runs a personalized fitness diagnostic based on your body type and goals, and creates a daily exercise to-do list with how-to guides. It tracks your weight over time and congratulates you when you're hitting your targets.

How we built it

I/ Lovable built it with React, TypeScript, and Tailwind CSS on the frontend, using Lovable Cloud for authentication (including Google sign-in) and user data persistence. AI-powered content generation (quotes, workout plans, daily exercises) is handled by backend functions that interface with large language models. State management uses Zustand, and animations are powered by Framer Motion.

Challenges we ran into

Getting the congratulations logic right, determining whether a user should gain or lose weight based on their goal, and comparing it against their weight history required careful conditional logic. Designing a clean, minimal UI that didn't feel cluttered despite having three distinct features was also a balancing act.

Accomplishments that we're proud of

A fully working AI fitness coach with personalized plans Expandable exercise guides with step-by-step instructions built into the workout list Smooth, minimal dark-themed UI with a cohesive green-and-white design system Google authentication with persistent user profiles

What we learned

We learned how to integrate AI APIs into a real-time user experience, how to design multi-feature apps that still feel focused, and how powerful modern tools like Lovable Cloud are for shipping full-stack apps fast.
