Hey Hunters! 👋 I'm Charles, maker of Schwarzy. I built Schwarzy because I was tired of workout apps with big subscriptions or 1000-step flow just to get started. Plus, after dealing with shoulder and elbow injury, I realized what was missing: an app that tracks not just WHAT you lift, but HOW it felt. Your body knows when form is breaking down or when you're ready to level up. Most trackers ignore this completely. The Problem: Traditional workout apps have two major flaws: 1. They make you guess whether to add weight or not 2. They store more data than they need to and own it Schwarzy introduces a pain-based progression system. After each set, you rate how it felt: • Flawless - Perfect form, explosive reps → App suggests +5kg next session • Strong - Solid reps, good control → Suggests +2.5kg • Compromised - Form breaking down → Maintain current weight • Pain - Risk of injury → Reduce 10% and rebuild It's like having a coach who actually listens to your body instead of blindly following a program. Key Features: 👻 Ghost Sessions - See your previous workout overlaid on your current one. Instantly compare sets, volume, and ratings to know if you're progressing. 📊 Visual Progress Tracking - Beautiful charts showing weight progression, volume trends, and form quality over time. 💪 Built-in Form Cues - Every exercise includes detailed form reminders so you never miss key technique points. 📱 Program Support - Import structured programs via JSON or create your own training splits. The app auto-rotates through program days. 🌙 Mobile-First Design - Dark mode, haptic feedback, wake lock (screen stays on), works fully offline as a PWA. 🔒 Privacy-First - All data stays on YOUR device. No cloud, no account, no tracking. Export/import whenever you want. Schwarzy is 100% free and open source: https://github.com/funkycharlie6..., so you're free to participate to improve it! No premium tiers, no paywalls, no ads. Just a simple tool to help you lift smarter. I'd love your feedback on: - What other pain points do you have with current workout trackers? - What features would make this indispensable for your training? - Any major bugs or UX issues you spot? I'll be here all day answering questions and taking notes. Would love to know if this is just a cool tool for me or if this helps other people train better. Thanks for checking it out! 🏋️ Charles
