Safeguard that most important (and misplaceable) scrap of paper — the grocery list — by putting it on your mobile device. Search for an item to get a range of results, both generic and brand- name, then file it in the appropriate supermarket aisle (Deli Counter, Snack Foods, etc.).
WIRED Scan barcodes of empty boxes to add them to next week's list. Sync a list with family members via a Grocery iQ account.
TIRED No way to search favorite items. Sharing has been glitchy in recent updates.
