GymCalc – A Strength Training Calculator

A lightweight iOS app that makes barbell math instant and customizable for strength training athletes.

Key outcomes

Working iOS prototype with custom equipment profiles and clean UI
Demonstrated how I combine product thinking with AI tools to ship real products quickly
Showed curiosity, adaptability, and proactive learning beyond my core design role

Problem

Barbell math slows down training, especially with different plate sets across gyms. Existing apps were either bloated or too rigid.

Solution

I built GymCalc, a lightweight iOS app that makes barbell math instant and customizable. Enter your target weight, and it outputs a clear plate breakdown based on your equipment.

Approach

  • Designed simple, focused flows for speed and clarity.
  • Prototyped logic in Replit, then built the app using Cursor with AI-assisted code generation.
  • Scoped tightly to solve one pain point really well: fast, accurate load calculations.

What I learned

This project taught me how AI-assisted development can accelerate prototyping while maintaining focus on user experience. Building a focused, single-purpose app reinforced the value of solving one problem really well rather than creating feature-heavy solutions.
