Features
Log every watering, feeding, and observation per plant. Entries are automatically timestamped and tagged with the current growth stage and week — no manual input required.
Capture your plant's journey with a stage-tagged photo diary. Every photo is timestamped and organised into a visual timeline so you can watch your grow progress from seed to harvest.
An on-device coaching engine provides stage-by-stage tips, pH/EC validation, and VPD calculations — fully offline. Upgrade to cloud AI (Claude) for natural language chat, photo diagnosis, and AI-generated nutrient plans.
Search a built-in strain database covering Sativa, Indica, and hybrid varieties. See flowering time, THC/CBD profiles, and ideal conditions. Add private custom strains visible only to you.
Log fertilizers with configurable detail — from basic product name to full pH, EC/PPM, and NPK values. Out-of-range values trigger an instant in-app warning with correction guidance.
Watering reminders adapt to your soil type and growth stage. Light schedule reminders fire automatically at key transitions. All notifications are local by default — push is opt-in.
Browse an offline library of common pests and diseases. Upload a photo for AI-powered diagnosis. Log treatments and track recovery with follow-up photos.
Completed grows are archived as self-contained journals with all diary entries, photos, and logs intact. Fully searchable, and exportable as a ZIP archive.
Privacy
GrassBuddy stores everything locally by default. No account required, no data leaves your device unless you choose to enable cloud sync — and even then, you stay in full control.
