It's rather unknown but I use it every week to do my grocery shopping. I think it's the first real innovative app for doing grocery shopping in years. It will use your headset and the text to speech engine to read your groceries. If you click the headset button it will read the next item. This way you have your hands free for picking. It also learns the optimal route once you sort your first lists in the best order. It's only available for Android: https://play.google.com/store/...
