PantryPalz

Most of us throw out food we forgot we bought: the spinach at the back of the fridge, the chicken that was meant for Tuesday. PantryPalz keeps a list of what's in your fridge, freezer and pantry and reminds you the day before something needs using.

Add a whole grocery shop from one receipt photo, scan a barcode, or point the camera at the printed date. The Today screen shows what to use first, and recipe ideas are built around what's about to go off. Your food list stays on your iPhone and works offline.

Free for a week, then $39.99/year, $7.99/month or $79.99 once. iPhone only for now. I'd love feedback from anyone who wastes more food than they'd like to.
