Reminders that arrive
One morning summary of everything due, plus an alert per plant with Done and Snooze in the notification. Gentle nudges when something is overdue.
Your plants, your schedule
Starting schedules for tropicals, ferns, succulents, herbs and more, all editable. Water, mist, fertilize and repot each get their own interval.
Watered it yesterday?
Mark it Done on… any past date and the next date follows the real one. Water every plant due in a room with one tap.
Winter mode
Stretch watering intervals for the slower, darker months, so you don't overwater when growth slows.
Rooms, notes and history
Group plants by room, keep notes, and see a care history for every plant by month.
Private by design
Works offline. No account and no sign-up. Back up to a file and restore it, at no cost.

Private by design

Questions
Does FernTimer tell me exactly when to water?
It starts each plant on an editable schedule for its type and reminds you when it's due. Check the soil before you water. If a plant is always still damp, lengthen its interval. Winter mode stretches intervals for the slower months.
Will reminders arrive if the app is closed?
Yes. Reminders are set again after a restart or time-zone change, and a reminder health check plus a battery guide help on phones that delay notifications.
Can a plant sitter use it?
Pro makes a vacation care sheet you can hand to a sitter, with what each plant needs.
Is it a subscription?
No. The free version holds 15 plants with a small ad. Pro is a one-time $3.99 unlock.
