A free iPhone app to monitor watering requirements for gardens designed by the University of Melbourne. Only weather/horticultural data for Melbourne and Geelong are available, so it's only suitable for people in these two areas.
"The app lets you view gardens that you have previously modelled using SmartGardenWatering.org.au, and reminds you when to water and for how long. It also shows you how much rain has fallen near your suburb so that you can make sensible decisions should the rainfall differ from the expected 'average'."
