Windowsill

A calm houseplant game, true to real plant care.

Water, repot and propagate real plant species in rooms that follow the time of day. What you learn applies to the plants in your own home.

The rooms follow the time of day.

Every plant has a care tag

Modelled on the tags in nursery pots, with advice that applies to the same plant at home.

At your own pace

Check in when it suits you. Plants change slowly, over hours and days.

Watering a bonsai fig on the porch: the watering can pours and the soil darkens

Hold to water

Press and hold to water, and the soil darkens as it takes up water. The game tells you when a plant has had enough, since overwatering is the most common way houseplants are lost.

A wall of shelves holding every plant in your collection, from pothos to cactus

Propagate from cuttings

Take a cutting from a mature, healthy plant, root it in water and grow it on. You can name each plant, and every plant you keep has a place on the shelf.

The plant shop: golden pothos, snake plant, apple cactus, Boston fern

Healthy plants earn dew

Dew is the game's currency. Healthy plants produce it over time, and you spend it on new plants, pots and rooms.

Rooms to fill,
one windowsill at a time

You start in the living room and add rooms as your collection grows. Each has its own light and humidity, and follows your local time, with lamps and string lights on in the evening.

Questions

For anything else, write to hello.waterme@gmail.com.

Is Windowsill free?

Yes. Windowsill is free to download on iPhone.

Is the plant care advice real?

Yes. Each plant's care tag covers light, water, temperature, humidity and pet safety, along with where the species grows in the wild. The advice applies to the same plant at home.

Do I have to play every day?

No. Plants dry out in real time, each at its own pace: a snake plant can go weeks between waterings, a fern a few days. Optional reminders tell you when a plant needs water, at a time you choose.

Can my plants die?

Yes, if they're left too dry or too wet for a long time. A wilted plant recovers over a day or two after watering. If one dies, you can compost it and keep the pot.

Does it work offline?

Yes. Your garden is stored on your phone and works without a connection.

Does Windowsill collect my data?

No. There's no tracking, and your garden is stored only on your iPhone. The privacy policy has the details.

Is Windowsill on Android?

Windowsill is available on iPhone first. If you'd like an Android version, email hello.waterme@gmail.com to let us know.
