Strain Memo
An offline-first, privacy-focused PWA for logging cannabis sessions, annotating effects and symptoms, and surfacing personal insights — all stored locally with no account required.
Overview
Strain Memo is a private, offline-first PWA built to track cannabis sessions without sacrificing privacy — no account, no backend, no analytics. The entry form takes under 30 seconds; richer annotation (effect, symptom, and flavor sliders, timed notes, tags) can be filled in after the fact.
