Long summer days. Short winter days. Sunna adapts watering reminders to your local daylight and your plant's place by the window. Start free with 5 plants.
Plant care that follows the light.
Sunna adapts watering reminders to your local daylight, from long summer evenings to short winter days.
Made in Norway, Sunna calculates day length for the location you choose and adjusts suggested watering intervals using the season and your plant's window direction and distance. See what's due today, keep track of what you've done, and set your own intervals whenever you want.
GET TO KNOW YOUR PLANTS
• Not sure what you've brought home? Take a photo for AI-assisted identification, then save the plant's story to its card.
• Yellow leaves or a drooping stem? Use up to 3 photos and tick what you've noticed for an AI health assessment with suggested next steps. Scan a plant in your collection to keep the result in its history and choose whether to add follow-up reminders.
• Looking for your next plant? Answer 4 questions and explore suggestions for your home and your care routine.
MAKE EVERYDAY CARE EASIER
• Keep watering, feeding, misting, leaf-cleaning and repotting together in your reminders.
• A home screen that moves with the sun where you live — dawn, day, golden hour and night, shifting with the season.
• Explore 273 plant entries with care information and soil advice, plus 8 guides on watering, light, winter care, repotting and pests.
• Organise plants by room, log care for several at once, and follow their progress with photos and a care journal. Add your own plants and edit any plant's care.

Care for 5 plants, with 3 identifications, 1 health scan and 3 share cards per month, and 2 saved photos per plant.

No account. No ads. No tracking.
Your collection is stored on your device. For optional AI identification and health scans, the photos you select and any care details you have recorded are sent to an AI service. We do not store those submissions on our servers — see the privacy policy for how they are handled. Back up through your device backup or a local export file.
Care suggestions and AI results are estimates and can be wrong. Sunna shows recorded pet-toxicity warnings; no warning means the plant has not been assessed. Never use Sunna to decide whether a plant can be eaten or used medicinally. If you suspect ingestion, contact a vet or doctor.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Your plant doctor listens better now. In a health scan, tick what you have noticed — yellow leaves, a droopy stem, a recent move — and the advice takes it into account.
The result stays with the plant: the assessment is saved to its history, and follow-up reminders are one tap away.
Reminders keep up when you move, rename or snooze a plant, and where a pet-toxicity warning has a source, Sunna now names it.
