## What is Sunna?

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.

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.

## Version history (last 5 releases)

### 1.9.0 — 2026-09-18

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.

### 1.8.0 — 2026-08-22

Sunna keeps growing:
• 273 species in the catalog — now with garden favourites: rose, peony, lilac, clematis and more
• Richer species pages: origin, height, temperature and propagation
• Smarter plant identification — honest suggestions when a photo is ambiguous; refine with a close-up or flower shot
• New search: best match first, right under the field
• Favourites: save species you dream of
• Follow-up tasks after health checks
• A prettier evening and morning sky

### 1.5.0 — 2026-08-18

Our biggest update yet — everything new since 1.2.1:

• Browse all 200 species with verified care data
• 8 care guides — watering, light, winter care, pests and more, now in every app language
• Identification 2.0: ranked matches to choose from, an identify history, and AI care advice even for plants outside the catalog
• Photos now save in full quality
• Watering snooze, undo for accidental taps, and schedules that account for distance from the window
• The free plan has grown from 3 to 5 plants, plus 3 free share cards a month
• Backup files now carry your identify history too

### 1.2.1 — 2026-08-14

The free plan now holds 5 plants (up from 3). A full review of our care data: more species now get a proper winter rest with gentler watering in the dark months, misting advice was corrected for plants that dislike wet leaves (cyclamen, Cape primrose and friends), and spring bulbs no longer get pointless fertilizer reminders.

### 1.2.0 — 2026-08-10

Archive a plant instead of deleting it. Archived plants leave your reminders but keep their photos, notes and history, and you can restore them any time from Tools.

Add your own note to any plant.

Identify a plant from your photo album, not just the camera.

The plant page is tidier, the tab bar stays with you as you move around, text is legible at dusk and after dark, and layouts hold at large text sizes.
