The Hiku from Hiku Labs is actually designed to help you make your grocery shopping list with some ease. However, Rich Brown (in the CNET video attached) feels a paper and pencil is just as good! The CNET video appeared in The Examiner's video stream on or about October 15, 2013. Getting back to Rich on the list comment - it seems just too likely that the Hiku software and app will expand to include other shopping activities. It is promised to soon provide online shopping experiences. It also seems likely that the Hiku will expand to include your holiday shopping needs - too bad the device/app may have missed this year's holiday "shopping fun"!
Here's another idea for the engineers at Hiku - include an input/output feature that tells you when your grocery items will or have expired? However, the app does not yet appear on the iTunes app store. According to Rich Brown's report you won't need to take your iPad with you to the grocery store? And, soon, it should also be available on an Android platform. Unfortunately the design is such that your 5 year old should be able to use the device too. Keep it well away from the kids, if you have any.
You can speak about your grocery needs to the device or you can scan the grocery item UPC codes. However, Hiku will not know all of those UPC codes. You can combine the speaking and scanning functions to include the hitherto unrecognized UPC code. Rich "reminds us that Trader Joe's is one of those exceptions to the use of UPC codes". Crowdsourcing from the cloud can help here if you are a local fan of Trader Joe's. (Google/Google Maps currently lists 3 local locations for Trader Joe's.) Rich's comment on the lack of UPC codes seems confusing - TJs reports that they installed checkout scanners in 2001?
Also surprising (to Rich) is that Hiku refers to it's hardware as "beta" stage - that caused him to question the MSRP of ~ "$79". Hiku is, however, a standard 802.11b/g/n Wi-Fi device. Another truly forward-looking thing about Hiku is that they use Zendesk Support. The Support page is worth checking out for more help about options from Hiku Labs Hiku grocery gadget.
