Apps, created with GenAI

Complete end-to-end applications built with Generative AI assistance throughout development — watch them in action below.

StrongLift — Gym Workout Tracker

A full-stack gym workout tracker (PHP, MySQL, vanilla JS PWA, Flutter) built with GenAI assistance: log sets/reps/weight, reusable templates with per-set targets, progress charts and personal records, body-weight tracking, and full offline support with automatic syncing. Available as both a Web app (PWA) and a native Android app — the offline-first Flutter client stores data in local SQLite and two-way syncs with the same backend.

Available as both a Web app and a native Android app — an offline-first Flutter client with the same features.
