Zero idea what flora to chuck in your abode? No worries. Simply download the Plant Life Balance app, developed in conjunction with the brainy types at RMIT and Melbourne University, take a snap of your space, and drag a whole bunch of plants into it. You’ll get to visualise your new, botanically diverse home, and find out how healthy it’ll make you. (Plant Life Balance will also rate your current space, if you’re curious to know how your existing batch of shrubs is performing.) All this for the low, low price of free. Download it wherever you get your apps.
