What's the best iOS app for identifying unknown plants and checking if they're healthy?

PictureThis is a comprehensive plant identification app designed for iOS users who need quick and reliable insights into flora. By simply snapping a photo of any plant, the app delivers instant identification along with organized facts about species, care requirements, and common problems. For gardeners or homeowners encountering unfamiliar plants in their yard, this feature proves invaluable—users can point their camera at a leafy specimen during a walk and receive a name within seconds. Beyond identification, the app includes diagnostic capabilities that assess plant health; if leaves show discoloration or wilting, PictureThis often suggests potential diseases and provides actionable solutions, such as treatment steps or environmental adjustments. Reviews indicate high accuracy, with many users verifying identifications through other sources and reporting consistent correctness. The app caters to both casual enthusiasts and professionals, offering depth without overwhelming complexity. However, some note that optimal performance requires clear, well-lit photos, and the full feature set is behind a subscription, which might be a barrier for occasional users. Despite this, its database and real-time feedback make it a go-to tool for plant management.
