Sunna – Plant Care

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. • Light meter — get an approximate lux reading at your plant's position, on phones with a light sensor. • 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. START FREE Care for 5 plants, with 3 identifications, 1 health scan and 3 share cards per month, and 2 saved photos per plant. Premium adds unlimited plants and saved photos, removes the monthly identification and share-card allowances, and includes up to 30 health scans per month. Online scans remain subject to daily fair-use limits. Premium is an auto-renewing subscription. 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.
