Cheapskate? There’s an app for that. Lots and lots of them, actually. There are iPhone apps that will plot a busy day of hitting yard sales, produce coupons for instant discounts at supermarkets, shops, and restaurants, do price comparisons and summon product reviews while you’re mulling the options inside a store, and even help you trim your bar tab.
Thirteen of these 20 money-saving apps are free, while the rest cost $3 or less. They should all be available at iTunes. For even more iPhone apps, check out Time.com’s Must-Have Apps page, with lists of the best apps for new moms, back-to-school, and beyond.
