Hey Product Hunt! 🚀 After over a year of development, let me introduce Gym Hero biggest update—a privacy-first, on-device intelligence-driven workout and health tracker for Apple users.
The Problem:
Most gym apps fall into two extremes:
1️⃣ Overcomplicated solutions with bloated features that resemble an exercise encyclopedia.
2️⃣ Basic tracking tools that force you to juggle notes, timers, and multiple health apps.
The Solution: Gym Hero
I built Gym Hero to bridge this gap—a native, Apple-first fitness tracker that combines intelligent workout tracking, deep health insights, and on-device AI—all while keeping your data private and offline.

@masump Hey Masum, Gym Hero is fully integrated with Apple Health. This means that HRV, sleep, and other data are specific to each user. Gym Hero simply uses an algorithm to compare these values with past trends and present a single, easy-to-read metric.

@jonurbonas hey Jonas, thanks for your message!
Right now, AI-generated workouts still rely on OpenAI. It’s the last thing I plan to migrate because it provides more variety and accuracy compared to a 1B/3B parameter model.
The process is pretty straightforward—you fill out a short questionnaire with a few questions, and the prompt is optimized to generate a workout routine that aligns with a set of parameters created alongside a certified personal trainer.
