The app is very fluid in its inputs and fast to use. I visit three markets, two farmers markets, Costco, and a little online shopping. Unobtrusive and fast to use to justify the time without being burdened by the data entry. Itd be nice if there was a tad more structure on the price and unit inputs so that it could auto notify if something is a better price elsewhere. Also, when visiting a store, itd be nice to mark a price as "last verified on". Cheers!
