I built a personal trainer app in a weekend. Big fitness apps beware.
I vibe-coded my own personal trainer and ditched multiple apps. It raises questions for big fitness apps.
TL;DR
- A custom personal trainer app was built in a weekend using AI, eliminating the need for multiple fitness tracking applications.
- The app, created with AI tool Manus, features a workout program generator, exercise library with demos, and the ability to log lifts.
- Vibe coding allows non-technical users to create personalized applications by describing desired features in plain English.
- The ease and affordability of creating such personalized tools may threaten the market share of large, established fitness apps.
- Hyper-personalization through vibe coding offers a competitive advantage over traditional fitness apps built for mass scale.
