Hey Product Hunt! 👋 I’m Ruslan, co-founder of VanzaLabs. Together with my partner, we build focused, privacy-first software. Today, we're thrilled to introduce SPOT — our precision workout tracker and muscle recovery engine for Android. 🏋️ Why we built SPOT: If you take lifting seriously, you’ve probably tried dozens of workout apps. Almost all of them suffer from the same problems: 1. They’ve evolved into bloated social networks with feeds, badges, and pushy subscriptions you never asked for. 2. They rely on blinding bright white UIs that burn your eyes in dark gym settings. 3. They fail completely in gym basements where cellular data drops to zero. 4. Most critically: they don't help you understand muscle recovery. You are left guessing whether your chest, lats, or hamstrings are actually ready for another heavy session, which often leads to overtraining or plateauing. ⚡ What SPOT does differently: • 🧬 Algorithmic Muscle Recovery Engine: Uses mathematical time-decay models per muscle group (0–100% readiness). Know exactly when a muscle is fully recovered to hit your next PR safely. • 📶 100% Offline Reliability: All routines, active timers, and set logs live on your device. Never lose a workout because your gym has poor reception. • ⏱️ Frictionless Live Session Tracker: Large touch targets, auto-suggested weight progression, and an automated rest timer with subtle haptic pulses and sound cues so you don't stare at your screen between sets. • 📋 Adaptive Routine Generator: Smart setups for Push/Pull/Legs, Upper/Lower, Full Body, and Arnold Splits tailored to your schedule and available equipment. • 🖤 Pure Dark Aesthetic & Zero Ads: True OLED dark palette with neon accents (#C8FF3D). No pop-ups, no video ads, and zero selling of your biometric or workout data. We built SPOT for lifters who care about progressive overload, mechanical tension, and actual results without distractions. We would love to hear your feedback, workout split preferences, and feature requests! What would you like to see in our next release? Get SPOT on Google Play: https://play.google.com/store/ap...
