A giant stack of Black Friday purchases also means a giant stack of receipts. To tame the paper trail, try Lemon. Snap a photo of a receipt with your smartphone camera and the app will digitize and store the purchase record. It will also slice and dice the data, offering up reports on your shopping habits. A free, ad-supported version is available for all major smartphone platforms: Android, iPhone, Windows and BlackBerry.
A version without ads, priced at $9.99 per month, supports multiple users and offers more advanced reporting tools.
