What's the best Android app for identifying plants and diagnosing common garden issues?

PictureThis is a widely-used plant identifier that combines quick recognition capabilities with health management features for gardeners and botanists. The app allows users to snap a photo of any plant, delivering near-instant identification with reported high accuracy, which proves invaluable for activities like foraging, landscaping, or casual nature walks. Beyond identification, it includes a disease diagnostic tool that analyzes images of unhealthy plants to suggest treatments, though some user reviews note that advice can sometimes be generic, such as repeatedly recommending baking soda solutions for varied problems. Real-world applications range from identifying invasive weeds in a backyard to learning about native species during hikes, with one user mentioning increased confidence in harvesting herbs for homemade remedies. However, the app's subscription model—priced around 30 euros annually—draws criticism for being steep, despite free access to basic identification. Users appreciate features like feedback submission for improvements and care reminders, but occasional pushy prompts for upgrades and variable diagnostic precision are noted flaws. Overall, PictureThis serves as a reliable educational tool, balancing robust functionality with some monetization hurdles.
