Mossu - Plant Care Reminder

Every plant parent knows the feeling: you swear you will remember when to water the monstera, and three weeks later the leaves are drooping and you cannot recall if you watered yesterday or last Tuesday. Mossu exists to end that guessing game for good, one plant at a time.

■ Watering reminders that fit each plant
Register a plant and Mossu computes the next watering day from species-specific intervals, adjusted for the growing season versus winter dormancy. Every reminder comes with a gentle "check the top 2 to 3 cm of soil first" guide, because the calendar is a starting point, not a rule that ignores what is actually happening in the pot.

■ A 209-plant encyclopedia
From Monstera to succulents, herbs, and orchids, look up watering needs, light, humidity, temperature, difficulty level, and repotting cycles for every species in the database. Pet owners can also check cat and dog toxicity info before bringing a new plant home.

■ Care calendar
See this month's watering, misting, fertilizing, and repotting schedule for every plant you own laid out in one calendar view, instead of trying to hold five different schedules in your head at once.

■ Growth journal
Capture the moments your plants grow, unfurl a new leaf, or bounce back from a rough patch with photos and notes, and give each plant its own profile photo so your collection feels like a collection, not just a list.

■ Offline, backed up, and multilingual
There is no server and no account required. Your data stays on your device, and you can export or import a backup whenever you switch phones. The app supports English, Korean, and Japanese, plus light and dark themes.

Who this is for
People who have killed a plant by forgetting it existed for a month. People who just bought their first Monstera and have no idea what "bright indirect light" actually means in their apartment. People whose windowsill has quietly grown into a small jungle and needs an actual system instead of sticky notes.

Common questions
Does it work for succulents and cacti too? Yes, the plant database spans succulents, cacti, tropical houseplants, herbs, and orchids, each with its own watering interval.
What if I do not know my plant's exact species? Search by common name or browse the encyclopedia by category to find a close match, then adjust the interval manually if needed.
Is the pet toxicity information reliable? It is based on publicly available reference sources such as the ASPCA and is meant as general guidance, not a substitute for a veterinarian if ingestion is suspected.
Does it need an internet connection? No, the app runs and stores everything locally on your device.
What happens to my data if I switch phones? Export a backup file before switching and import it on the new device to bring your whole collection over.

■ A typical week with Mossu
Monday morning the app tells you the fiddle leaf fig is due, so you check the soil, confirm it is dry two knuckles down, and water it. Wednesday a gentle nudge for the pothos comes in, right on schedule for its faster-draining pot. By the weekend you open the growth journal, snap a photo of a new leaf unfurling on the monstera, and realize you have not lost a single plant to neglect in months, not because you got better at remembering, but because you stopped having to.

■ Why species-specific intervals matter
A one-size-fits-all "water once a week" reminder is exactly how plants get overwatered or underwatered. A succulent and a fern have almost nothing in common in terms of thirst, and even the same plant needs less water in winter than during its growing season. Mossu builds each schedule around the actual species and the time of year, not a generic countdown.

You can track up to 5 plants without any purchase. Beyond that, a one-time purchase unlocks unlimited plants for life. Add your first plant today and let Mossu handle remembering so you can focus on growing.
