Press ON to open the Settings pane.

Figure 1: Settings pane. Press ON to open this pane.

In this pane you also find the options to save/load/delete copies of the memory to files, and change the RPN flavor. Other configurable items:

Number format: decimal and thousand separators. Three formats are available: USA, European and Indian.
Key feedback: emission of sound and/or vibration (haptic) on every keypress.
Visual key feedback: when active, shows a small green rectangle when a key is pressed.
Layout orientation: When configured to "Auto rotate", the layout follows the phone orientation. If configured to "Landscape" or "Portrait", the layout is locked to horizontal or vertical, respectively.
Fullscreen: When activated, the status bar is hidden, making more room for the app.
Stretch display: Dictates how much the interface is "stretched" to fill most of the screen. Maximum stretch uses the whole screen and makes keystrokes easier, but distorts the appearance.
Do not sleep: When activated, the phone will not sleep automatically while the calculator is open.
Rapid program execution: When activated, programs will run at maximum possible speed. When turned off, speed is similar to a real calculator.
Reset to defaults: Reset all configurations to the post-install defaults. Even the calculator flavor goes back to Financial with ads. (Purchases are always preserved, and memories saved in files are not deleted.)
