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.

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.

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.
