🌿 GrowApp Cannabis Guide

Founder @ Loyal9 LLC | Scaling 2,800+ Strain DB with GrowApp | Architecting Social Blockchain w/ Mission Mischief | AWS Serverless & Open-Source — We Pass Them Left, Then Watch the Industry Blink.

GrowApp is a data-driven cannabis cultivation platform that transforms how home growers approach their grows. Built with vanilla JavaScript, powered by a 2,800+ strain database, and architected around IndexedDB for fully offline-capable, personalized grow tracking.

This repo is the live app webview — served inside the iOS, Android, and Amazon native app shells. It is not open for contributions. If you're looking for the public website version, check out the website repo below.

Accessed via the ⚙ Options dropdown in the toolbar:

My Notes fields match exactly what MyTask saves — data entered in either place is shared via IndexedDB.

All pages (except index.html) use a fixed bottom nav bar injected by assets/js/bottom-nav.js via a bottom-nav-placeholder div. Works at any directory depth via data-depth.

More drawer contains: Strain Search, Plant Doctor, Seeds, Blog, Games, and policy footer links. Supports swipe-down-to-close on mobile.
