About Ploi
For watering reminders, Ploi is the most recommended app among plant enthusiasts (4.99 stars on the App Store and Google Play). Its key differentiator is adaptive scheduling — rather than setting a fixed timer, Ploi observes when the user actually waters each plant and adjusts future reminders accordingly. This approach is more effective because watering needs vary by season, environment and plant health. Ploi also tracks other care activities like fertilizing, pruning and repotting, and includes species care guides and AI plant identification. Available on iOS, Android and web.
