Ans is a proper scientific calculator: a dedicated instrument that opens instantly, works entirely offline and treats your mathematics with respect. It brings back the feel of the calculator you trusted at school — real keys, a clear two-line display, an answer you can carry forward — thoughtfully modernised for iPhone, iPad and Mac. EXACT WHEN IT MATTERS Fractions stay fractions: with A = 3/4 and B = 2/3, (A+B)×(A−B) is exactly 17/144, not a decimal pretending. π is kept exact, so sin(π) is 0 — not almost 0. Every answer can switch between its exact and decimal forms with one key, and you can copy either. BUILT AROUND YOUR ANSWER The app is named after its most useful key. Press an operator after any result and Ans carries it into the next expression — exactly, with nothing rounded away. Step back through earlier calculations with the replay keys, edit any expression in place, and evaluate again. A COMPLETE SCIENTIFIC TOOL Trigonometry in degrees, radians and gradians. Logarithms and exponentials. Powers, roots of any degree, factorials, fractions, percentages, scientific notation with proper superscripts, a random-number key, independent memory and parentheses that behave the way a dedicated calculator's do. SEE IT IN ACTION A one-minute Quick Tour demonstrates SHIFT, variables, the VAR hold that opens the Variable Explorer, built-in physics constants and exact fractions on the calculator itself, with the keys pressing as you watch. Take it on first launch or replay it at any time from Settings. With haptics enabled, VAR responds lightly on touch and more firmly when the explorer opens. The tour is on iPhone and iPad; on Mac, the built-in guide in Help covers the same ground. SIX VARIABLES, REMEMBERED EXACTLY Store values in A to D, X and Y through the classic STO flow, give them names like "gravity", and inspect them without leaving your calculation. Or choose from 15 built-in physics constants — including the speed of light, Planck constant, gravitational constant and particle masses — using current 2022 CODATA values. A stored 1/3 stays 1/3, across launches. YOUR ANSWERS, ALWAYS CLOSE Home Screen widgets in three sizes page through your recent calculations with calculator-style keys, and can open the exact one you select. A Lock Screen widget keeps the latest answer in view, and a Control Centre control opens Ans in one tap. MADE FOR IPHONE AND IPAD The complete face, always ready, on iPhone. A centred instrument with room to think on iPad — every orientation, Split View beside your notes, and hardware keyboards mapped the way you would hope: digits, operators, Return for equals. MADE FOR MAC A real desk calculator beside your work: a compact window that can keep itself in front while you write in the document behind it. Type calculations straight from the keyboard — Return for equals, ⇧ while clicking for shifted functions, ⌥ for variables — and open all six variables in their own window with ⇧⌘V. Native menus, native Help, the same exact engine. A CALCULATOR YOU CAN OWN Buy Ans once and the whole calculator is yours. No subscriptions. No ads. No accounts. No tracking. No locked functions. Ans itself makes no network connections — your work stays on your device, and the privacy policy is one page long. Built by one person who wanted a calculator worth keeping.

It’s fast, clean, and intuitive, with a layout that’s easy to use whether you’re doing quick calculations or more complex ones. I especially like that it opens instantly, has no unnecessary clutter, and feels reliable every time I use it. It’s become my default calculator app, and I highly recommend it to anyone looking for a simple but powerful calculator. ## Frequently asked questions about Ans ### Does Ans have ads?

Ans is available on Mac, iPhone, and iPad. It is optimized for each platform, offering a seamless experience across your Apple ecosystem. ### How does Ans handle fractions and constants? Ans treats fractions and constants like pi exactly, not as approximations. For example, it will display sin(π) as 0, not a decimal close to zero, and fractions remain in their exact form. ### Can I edit previous calculations in Ans? Yes, Ans allows you to step back through earlier calculations using replay keys. You can then edit any expression in place and re-evaluate it, ensuring accuracy. ### What is the age rating for Ans? Ans has an age rating of 4+. This indicates it is suitable for users of all ages, with no mature content. ### How often is Ans updated?

While specific update frequency isn't detailed, this indicates active development. ## Version history (last 4 releases) ### 1.3 — 2026-08-03 See Ans work, then put real-world constants to work. • A Quick Tour demonstrates SHIFT, VAR, keeping and using variables, holding VAR to open the Variable Explorer and browse physics constants, and switching between exact fractions and decimals. It runs on the calculator itself, with the keys pressing as you watch, and can be replayed from Settings at any time. • Set any of the six variables from 15 built-in physics constants, including the speed of light, Planck constant, gravitational constant and particle masses. Choosing one stores its 2022 CODATA value and a helpful label. • Touch and hold VAR opens the Variable Explorer sooner, and — with Haptic Feedback on — answers as you touch the key, then confirms when the hold completes. • Help now explains calculator errors, percentages, random numbers and hardware-keyboard input. ### 1.2 — 2026-07-26 Accessibility improvements for clearer reading. • Large SHIFT and VAR Labels — a new option in Settings. With it on, pressing SHIFT puts each orange second function on the key itself at full size, and pressing VAR does the same with the variable letters. The key's usual function moves into the small label above it, so nothing goes unnamed. • Large Display Text and Large SHIFT and VAR Labels now live together under an Accessibility heading in Settings (and in the Mac View menu). • Both options are off by default and do not change how the calculator works. ### 1.1 — 2026-07-25 Ans is now on Mac. One purchase brings the same exact calculator to iPhone, iPad and Mac — nothing new to buy. • Factorials, on SHIFT ) — so 8!÷(3!×5!) is one line of keys • Key presses now respond with feedback matched to what the key does • Refinements under the hood; everything else works as before. ### 1.0 — 2026-07-24 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
