What's New in PocketCAS

2026.3

October 27, 2026

PocketCAS now supports iPhone Duo. On iPhone Duo: - Open in landscape, and your document sits on the left page. The right page holds the editor with the math keyboard, or a plot. - Tap a plot in your document to open it on the right page, next to your calculations. When you edit a plot, it redraws as you type. - In full screen, a plot's buttons and legend sit in the vertical bar, out of the plot's way. - Open in portrait or in tabletop pose, the text is on the upper half and the keys are on the lower half. In tabletop pose, a plot stands on the upper half, with its functions, the traced point and the value table below it. - If you want the document across both pages, choose Wide Document in Settings > iPhone Duo > When Open. - Closed, PocketCAS works as on any other iPhone. On every iPhone and iPad: - With a hardware keyboard, Tab moves to the next argument only inside brackets. Elsewhere it types a tab, so you can indent comment lines again. If something works differently from what you are used to, or you find a problem, please write to me.

Geile Funktionen

Wenn man so wie ich keinen Plan hat, wie das Ding (Die Funktion) verläuft, dann ist, dies schon sehr geil dargestellt! Funktion der App super gut ! Deshalb 5/5

Jetzt ok!

Nach Info durch den Hersteller nun mehr Klarheit.

Leider sind manche Fehlermeldungen wenig aussagekräftig, aber die App scheint ziemlich gut zu sein. Man muss sich wohl nur in die Bedienung hineinfinden.

Response from developer

Rechts oben auf dem Bildschirm befindet sich eine Taste namens "Berechnen". Bitte drücken Sie diese Taste, wenn Sie etwas berechnen wollen.
