FitLog X is a privacy-first, zero-friction workout tracker I engineered after getting completely fed up with modern gym apps holding my data hostage. I wanted a pure utility tool for my own lifting routine, but instead, every app I found was riddled with corporate bloat, subscription paywalls, and mandatory cloud accounts forcing me to upload my sensitive biometric data to a server. To fight back against that subscription fatigue, I built a strict offline-first, local-only alternative that requires zero account registration, has no cloud syncing, and features no tracking scripts. Every rep, set, and metric you track stays entirely on your own device where it belongs.

Built natively using Kotlin and Jetpack Compose, I designed the app with a high-contrast, lightning-fast UI that boots instantly on the gym floor and won't drain your battery. FitLog X offers completely unrestricted, unlimited custom routine creation, professional-grade volume tracking, and deep progressive overload analytics completely free with zero ads. I built this to be the antidote to mainstream fitness tech—a clean, fast, and secure tool designed by a lifter, for lifters who want absolute data sovereignty.
