Dibble's answer
Dibble turns a location into a schedule. Enter a ZIP or postal code and it finds your hardiness zone and typical frost dates, then works out the start, sow, transplant and harvest windows for every crop you grow. The same calculations run on the website and in the app, so the dates agree wherever you check them. It also works without an account. There is no sign-up, no email and no password, your gardens stay on your device and sync through your own iCloud, and nothing is tracked or sold.
Dibble's answer
Three things. The dates are specific to where you garden, because they come from your hardiness zone and local frost dates rather than general advice. The app asks nothing of you before it is useful, since there is no account to create. And the free tier stands on its own: the planting calendar, reminders, crop library and journal are all free, with Premium adding the bed planner, plant disease diagnosis, harvest tracking, perennials and weather alerts.
Dibble's answer
Home vegetable gardeners. Mostly people growing food in beds, raised beds or containers who want to know when to start seeds indoors and when to plant out. It suits beginners who want the dates worked out for them, and experienced growers who want to log what they planted and compare one season to the next. Dibble covers the United States, Canada, Australia and New Zealand, and works in English, Spanish and French.
Dibble's answer
The iPhone, iPad and Apple Watch apps are written in Swift with SwiftUI, using SwiftData for storage on the device and iCloud for sync, so no server holds your garden data. The website is a statically exported Next.js and React site. The planting date calculations follow the same rules in both places, which is why the site and the app never disagree.
