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

Verdict
The clearest difference is in-app purchases: Dad's Calculator at none against ProCalc's 4. Dad's Calculator also leads on ads (none vs shown) and update cadence (every 2 days vs monthly). ProCalc's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
