CAL_ vs Snapculator

CAL_ is the next evolution of calculators. Made especially for iPhone, it brings the venerable calculator to an all-new level. LOG FEATURE All of your calculations are logged, so you can refer to them at any time. Use the ANS key to bring up the most recent result from the log. You can toggle commas and decimal points, and also use a guide that shows you when your units are in the millions, billions, and beyond. CURRENCY CONVERSIONS Get real-time currency rates for up to three currencies at once. You can also see a graph of currency value fluctuations. UNIT CONVERSIONS Want to know how many Tokyo Domes there are to an acre? Or how many lbs make up a stone? It's right at your fingertips in CAL_.

• Photograph a page and the figures it reads are calculated for you (photos from your library work too) • Every figure it reads is underlined on the photo. The color of the underline shows at a glance which figures were counted, which were left out (dates, addresses, document numbers), and which are worth a second look. • On a table, it recognizes the columns — unit price × qty = amount and the like — and warns you when what it calculates doesn't match what's printed. • If it read the wrong part of the page, you can point out the area you want read. • When something couldn't be read at all, you can add the figure yourself while looking at the photo. • A plain calculator is built in, so this one app covers it when you just want to work something out on the spot. • To work a scanned total against another number, a calculator opens across the bottom half of the screen, so you can keep calculating with the photo still in view.
