It works wonderful. I have 30 plants of different varieties, so they all need water at different times. You can add different locations in the app (living room, bedroom, balcony, etc) and then you add the plants. Every day the app notifies me which plants need watering. I still need to check as you mentioned, but it has been very useful. I also have some self-watering pots with little windows, so I don't use the app for those.
