The user wants to be able to scan a barcode and see the price of the product at other stores.
So a while back I was out shopping with my wife and grabbed a Pepsi Max for €3. Went to next shop and they had 3 for €5. I know it's petty, but it annoyed me so much that I started building this app Originally I wanted to make a barcode scanner that just tells you the price at other stores, but getting barcode data is surprisingly difficult, there's no good public database for it. So instead I built a shopping list with price comparison. You can search for a product and see the prices from Tesco, Dunnes, Lidl, Aldi, SuperValu and Centra. *Lidl, Centra is current deals only.* You can: * Compare prices * Check current deals and multibuy offers * Have shopping lists with running total * Share shopping lists with QR code * Check leaflets, save clubcards, coupons Android only for now. I can build it for iOS, but I didn't want to pay the €100 Apple developer fee until I know people actually care about the app. [Play Store link](https://play.google.com/store/apps/details?id=com.cisean.cisean), or search for "Cisean - Shopping List Ireland". It's free, no ads. I know there are some bugs and I want to add features like: barcode scanner, price history charts, organize shopping list by aisles (my wife do this for me sometimes and I spend half as much time in the store) Would love to hear any feedback or suggestions UPDATE: Added barcode scanner and many other suggestions from this post.
