No "water it TODAY" alarms
Watering comes as a window, not a date. Saturday or Monday — your pace still counts as on time.
A watering journal for houseplants
Never wonder "when did I water it?"again.
Green Logs learns each plant's rhythm and gently tells you when it's time. Log with one tap, share with your family.

Today – ThursdayHello
Made by someone who kept killing plants.
A snake plant. A pothos. A money tree. I've lost more plants than I can count.
The soil would go bone-dry — then I'd panic-water every day and rot the roots. I could never answer "when did I last water it?"
It was never about love, or memory. I just didn't have a record.
So this app never rushes you and never scolds you. It simply whispers "around now" — within a comfortable window.
For the one I couldn't keep alive.
— the person behind Green Logs
Designed to be gentle
Live with your plants,at a comfortable distance
Just three mechanisms, so it works without willpower.
"Watered!" is a single swipe
Swipe today's card to the right — the next window recalculates itself. Photos are only for the days you feel like it.
"Not recorded yet" is fine too
You can start with a blank history. Miss a day? No guilt-trip notifications, ever.
The plant guide
We looked up the "just right" for 100 species already
Watering rhythm, placement, common troubles — all in a guide, each species with its own hand-drawn icon.
Together
Share the plants,with your family
Up to 5 people share one plant list. When someone waters, that day's reminder takes the day off. "You don't have to carry it all alone" — built right in.
