PocketCAS for Mac

New

• When a calculation has no value, PocketCAS now says why instead of showing [ ] or undef: No real solution, No solution found, Undefined, Diverges, No limit or Unknown function, with a short reason below. A suggestion offers the next step, such as the complex solutions, the limits from the left and right, or a plot.
• PocketCAS marks a typing error in the input, and a suggestion offers the fix: sin x becomes sin(x), and intergrate becomes integrate. A stopped calculation shows how long it ran and offers Calculate Again.
• Next to an exact result, the ≈ line now also shows the decimal value of a result with units and of an integral without an exact value. Very large and very small numbers read as 2.43 × 10¹⁸ instead of 2.43E+18.
• When rounding changed a decimal result, the suggestion Exactly shows the exact value.
• Results and inputs show large numbers in groups of three digits, such as 1 234 567. Settings > Digit Grouping offers another separator, or none. The editor and copied text keep plain digits, and a number too long for the window continues on the next line.
• The Extrema suggestion now finds minima that it missed before, such as the one of abs(x) at 0.
• Clearer calculation steps for some integrals and for extrema, and a step that is too wide for the window continues on the next line.
• Plot Settings show a curve's color even when it is not in the list, as Custom Color.
• VoiceOver reads ( and ) as parentheses instead of braces.
• Clearer German and French texts, and a suggestion now adds just its calculation, without a comment line above it.
• The previous version of PocketCAS still opens your documents. It shows the new reasons as plain text next to the result.

Changes

• Suggestions under your results: the derivative, zeros, extrema and more, with the answers already shown. Click one to add it to your document. Settings > Suggestions turns them off or shows them only under the newest result.
• A small plot appears next to a function's result. Click it to add the plot.
• Calculation steps show how PocketCAS works out derivatives, integrals and a few other calculations.
• Results look like a math textbook, and long results wrap to the width of the screen.
• Clearer 2D plots with a finer grid, and 3D surfaces with soft light, shading and a floor grid. Rest the pointer on a mark to read it.
• A plot can open in its own window.
• Vector field plots: enter [f(x,y), g(x,y)] in a plot.
• A new look for the keyboard panel, with one key per function.
• On macOS 26 and later, PocketCAS uses Apple's new design, Liquid Glass, and has a new icon.
• Brackets close by themselves, and printed documents break long lines at the page's width.
• Plots now use seven curve colors, so a 7th or later curve in an older document may get a new color.
