Aerko_

Aerko_ is a local-first, privacy-focused Progressive Web App (PWA) designed to replace bloated fitness and nutrition trackers like MyFitnessPal or Hevy. Built entirely without frameworks (100% Vanilla JS), it ensures your data stays exactly where it belongs: on your device.

Key Features:

• 100% Offline & Local-First: All your workouts, macros, and progress are stored locally via IndexedDB. No cloud databases, no tracking, no accounts required. It works perfectly even in a gym basement without an internet connection.

• Free Nutrition Tracking: Integrated with the Open Food Facts API for a completely free, community-driven barcode scanner.

• Embedded AI Form Analysis: Uses Google's MediaPipe AI directly in the browser (via Web Workers) to analyze your exercise technique without ever uploading a video to a server.

• Smart Progression: Automatic e1RM (estimated 1 Rep Max) calculations to help you manage progressive overload efficiently.

• Neo-Brutalist UI: A bold, high-contrast design with a custom numeric keypad specifically engineered for easy tapping with sweaty hands during a workout.

Aerko_ is 100% free, has zero advertisements, and its code is source-available for complete transparency.
