A few things before you start
When can I download Grenny?
Grenny is getting ready for the App Store. There is no public download yet. The app is designed for iPhone with iOS 18 or later, in English and Russian.
What is included for free?
Care for up to 3 plants, with reminders, widgets and the photo journal included. For a larger active collection, choose monthly, yearly or lifetime access in the app. Apple shows your regional price before purchase.
Does a reminder always mean it is time to water?
Check the plant and soil first. A reminder tells you when to check, and you can postpone it if the soil is still moist. Grenny does not measure soil moisture or determine it from a photo.
Can I use Grenny without AI or internet?
Yes. Add plants manually and use saved local care offline. AI analysis is optional and needs internet. Your photo is sent to NovaSynapse and Google Gemini only after separate confirmation. Review the suggestions before saving.
What if paid access ends?
Choose 3 plants for active care. Your other plants and their history remain available to view. Subscriptions renew until cancelled in your Apple Account. Lifetime access is a one-time purchase. Purchases can be restored in the app.
AI analysis uses your photo only after confirmation. Manual entry and saved care work offline. Privacy policy
