I built this app because I wasn’t finding a logger that treated lifting like lifting. Most apps pushed gamification, AI coaching, and social features that got in the way. So I built the app I actually wanted in the gym. That means a completely free app for experienced and serious lifters. No social features, no gamification, no internet required for logging, and no AI. I didn’t want another app trying to motivate me or tell me how to lift. I wanted to build my routines the way I wanted, log sets easily with the features I wanted, and look back at honest training history. PRMaxxing is that. What you get with my app * Fast set logging built for the gym * Full routine control: set types, rest timers, supersets, unilateral logging and more * Honest history you can edit, with real PR tracking * Automatic progression schemes * Many graph types and tracking tools that show real progress * Warmup presets you can tune your way * Completely free, with no accounts, and no data tracking.
