HousePlantOS

Your urban jungle, organized. HousePlantOS is one private app for houseplant collectors - every plant gets its own card with nickname, species, room, last-watered date, next-water countdown, and a color-coded status stripe. The dashboard shows overdue (red), water today, due in next 3 days, and fertilize this week. A built-in library of 50+ common houseplants (Monstera, Pothos, Snake Plant, Fiddle Leaf Fig, Calathea, Orchid, Hoya, ZZ Plant, and more) with accurate light, water frequency, humidity, pet-toxicity, and difficulty data. Click any species to add a plant to your collection. Per-room view with window direction and light level drives placement and species recommendations. Per-plant detail modal logs every water, fertilizer, repot, pest incident, and growth note on a timeline. Runs entirely in your browser - no subscription, no login, no cloud.
