Calculator rethought: calculate, comment and correct instantly.
CalcTape is the calculator that works the way you think: type your whole calculation, see every figure, and change anything at any time. What if a standard calculator, a classic desktop adding machine, and a notes app were rolled into one? That's CalcTape - your companion for everyday math, from a quick sum to a long, multi-step calculation. (CalcTape is not a scientific calculator - and for daily use, who really needs one?) Ever run a long calculation and wondered: "Did I enter that last number correctly?" "Why does the result look off?" With CalcTape you keep the full overview. Every number and operator stays visible, so you can check your work - and correct any figure right in place, with all following results updating automatically. Forgot a value? Just add a new line where it belongs. Place the cursor anywhere in the calculation and edit it freely, like a note. The moment you change a number or an operator, everything recalculates. Think of it as a spreadsheet with a calculator interface. WHY YOU'LL LIKE IT • Edit any figure in place - results update automatically • See your entire calculation, not just the last result • Comment your numbers and results so it still makes sense weeks later • Build reusable templates: swap the figures, get the answer in a breeze • Percentages, thousands separators (including Indian digit grouping) • Day, Night and System themes • Reliable Undo/Redo and smooth editing, even in long calculations MAKE IT YOURS Keep only the buttons you actually use on your keypad, and create your own functions - for example, add a specific percentage with a single tap. FREE VS PRO CalcTape comes as a free version with the full tape calculator on your worksheet. The Pro upgrade adds: • Save calculations as documents and manage multiple files • Import, export, backup and restore • Print your calculations • Share via email and other apps • Unlimited variables • Fully customizable keypads — reassign any button, change button sizes, create your own • Multiple keypad layouts, including a numbers-free function keypad (three keypads are reachable right from the main screen) Found a problem or have an idea?
