iOS: Not everyone has a green thumb and keeping plants alive indoors can often be a fruitless act for those of us who can't remember to water, let alone care for a plant properly. If your thumb is more black than green, Koubachi is an iOS app that helps you keep your plants alive and well.
Unlike setting up a simple reminder system to water your plants, Koubachi requires some calibration on your part. When you first load up the app, you're required to select your plants from the app's database and then track the amount of time it takes for the soil to dry. From there, Koubachi uses your geographical location and soil data to send push notifications to remind you when a plant needs watering, misting or fertiliser.
If you're not an iOS user, there is also a webapp available in beta, that offers the same functions. Even if your home is filled with some of our favourite unkillable plants, it's still a handy and simple way to track and keep your plants alive. Koubachi is a free download in the iTunes App Store.
