Dad's Calculator
Read full descriptionHide full description
Dad's Calculator is for the moment you reach for a calculator in your everyday life: the checkout line, the measuring tape, the stove. It keeps a notebook of everything you work out, adds up the lines you pick, and remembers them for next time. Right next to it: a unit converter, a recipe scaler and size charts. THE CALCULATOR • Every calculation stays in a notebook-style history. Your math, with receipts • Percent works the way you say it: 80 - 25% = 60 • Pick the lines you care about and get their sum, average, largest and smallest • Copy the result, or drop the sum straight into your next calculation • Name a set of lines (groceries, measurements, quotes) and save it for when your memory lets you down • Swipe a line away, or wipe the whole slate WITHIN ARM'S REACH • Converter: type one number, see every unit at once. Star the ones you use • Cooking: recipe for 4, dinner for 6? Change the servings, or match one ingredient, and the rest follows • Sizes: shoes and clothes in US / UK / EU / cm, because sizes never agree • Notebook by day, chalkboard by night. Switch anytime in Settings SECRET DIARY • Log measurements for each body part and your weight, in cm / inches and kg / lb • Compare with 1, 3 or 6 months ago, in a graph or a table
