For a while I wanted to write an app that'd send you reminders when it was time to water your plants (based on factors like the plant type, the weather, etc...) but there are just too many vagaries to make accurate predictions. IE, your house may be particularly dry due to your particular AC unit, and so you may need to water twice as often as someone with higher humidity. This, on the other hand, makes a lot more sense.
