Hey Product Hunt 👋 I built GymMatrix because I kept forgetting to log sets. Pulling out my phone mid-workout, finding the exercise, tapping through weight and reps — it breaks focus, and with chalk on your hands it's genuinely annoying. So I'd just... not log. Then I'd have no idea what I lifted last week. So I made the logging disappear. You hold a button and say your set the way you'd tell a training partner — "squat 225 for 5" — and Gemini parses it into a logged set. No menus, no typing. Built solo over 8 months in Flutter. Some things I learned: - Forcing a rigid "exercise, weight, reps" format felt robotic — letting the AI handle natural speech was much better - Six App Store rejections taught me more about subscription compliance than any doc - Your own test account is the worst possible test account Free tier covers complete voice + manual logging, PRs, and history. Pro ($2.99/mo) adds AI program generation, form guides, and a weekly AI coaching report. I'd genuinely love feedback — especially from anyone who's abandoned a workout tracker before.
