I have had many different barcode scanners over the years and I think that they are a fun novelty at first but soon end up being uninstalled for lack of use. The one barcode scanner that I probably used the longest was Calorie Counter by myfitnesspal. It was pretty cool to be able to scan anything prepackaged that you were going to eat and see all the nutrition facts. It also allows you to keep a food diary that way but since I don't count calories and now avoid all packaged food, this too got quickly uninstalled.
I put Google Googles in the same category as the barcode scanner, a fun novelty but not something that you are actually going to use on a regular basis.
Google search is pretty basic and useful but I'm more of a Bing girl.
I could see stand app being useful but I spend most of my day on my feet, so its just not a good fit for me.
I have used my phone as my alarm clock for probably the last 15 years, so i decided to download this app and give it a try. I will update on how it goes shortly.
WiFi finder is a good idea but I don't have a lot of use for it. I'm almost always at home or at work and the few moments that I'm not in those places, I'm running in and out of the grocery store. I just don't have time to go to the local coffee shop and play on my tablet. Lol
