Anvil Workout: Plan your workout. Follow the flow. Track your progress.

👋 Hey Product Hunt! I'm Jarl, solo dev behind Iron Workout. I've been lifting for years and got tired of the same pattern: every gym app wants a subscription, an account, and a cut of my attention. I just want to plan a workout, log my sets, and see if I'm actually getting stronger. That's it. So I built the app I wanted for myself: 🏋️ Iron Workout is a strength training app that does one thing well: help you train and track progress. What makes it different: One-time purchase. No subscription, no "unlock premium", no free tier holding features hostage. You buy it once, you own it. No account required. No email, no login, no cloud. Your data stays on your iPhone. Fully offline. Gym basements, airplane mode, whatever — it just works. Zero tracking, zero ads, zero data collection. The privacy policy is short because there's nothing to explain. Native iOS. Built in SwiftUI with SwiftData. Live Activity on Lock Screen + Dynamic Island during workouts. Widget for your streak. HealthKit sync for calories and heart rate from Apple Watch. Automatic PR detection. Every time you hit a new personal record (more weight or more reps), the app flags it. No manual logging. Under the hood: Custom program builder with sets, reps, weight targets, rest timers, and supersets Charts for training volume, weekly frequency, and estimated 1RM progression CSV export so your data is always portable 25+ built-in exercises, add your own kg / lbs toggle, light/dark mode This is v1.0 and genuinely the result of me scratching my own itch. I'd love your feedback — what's missing? What do you hate about your current workout app that I could fix? Happy to answer any questions about the build, the design choices, the "no subscription" math, or anything else. Thanks for checking it out 🙏 — Jarl (IAMJARL)
