About this app

Thirstly is a plant care reminder and houseplant tracker that learns each plant's own watering pace. Water on your plants' schedule instead of a chart. Fully offline: no account, no ads, no tracking.

A watering reminder that learns
Add a houseplant in a few taps: a name, a room and how often you think it drinks. Thirstly starts there. After three drinks it works out that plant's real pace from when you actually watered, and the watering reminders follow. A plant that dries out faster in summer or a thirsty fern on a sunny sill gets its own schedule.

Who is thirsty today
Today shows every plant that needs water now. Check one off with a tap, with Undo. Mark it "still wet" and the schedule adjusts. Water a whole room in one go with Room check: hold to water, plant by plant.

Plant care beyond water
Feeding, misting, turning, pruning and repotting, each on its own schedule. A daily digest at the time you choose, or a note per plant. Season mode by date and hemisphere. Watering days, if you only water on weekends.

A journal for every plant
A photo timeline with a before and after slider. Notes, problems and pot details. Tags, filters and a wishlist. A care calendar that shows the year, plus streaks and badges for keeping up.

Rooms
Group plants by room and see at a glance which rooms are fine, and until when.

Private by design
Your plants, photos and history stay on your phone. The only time Thirstly goes online is for a purchase and, if you turn it on, backup to your own Google Drive.
