| Contains 13 historical, archaic, and unusual functions. They are: Versine (VERS(X); 1 – cos x), Coversine (COVERS(X); 1 – sin x), Haversine (HAV(X); sin(x/2)^2), Normalized Sampling (NSINC(X); sin(π * x)/(π * x)), Exsecant (EXSEC(X); sec x - 1), Gundermannian (GD(X); atan(sinh x)), Inverse Gundermannian (INVGD(X); asinh(tan x)), Dilogarithm (DILN(X); ∫ (ln t / (t – 1) dt, 1, x)), Exponential Polynomial (EPOLY(N, X); Σ(x^j / j!, j, 0, n)), Hypotenuse of a Right Triangle (HYPER(A,B); √(a^2 + b^2)), Langevin Function (LANGEVIN(X); 1/tanh x – 1/x), General Mean Function (GENMEAN(N,A,B), N = 1, arithmetic mean, N = 2, root mean square, N = -1, harmonic mean, (a^n + b^n) / 2)^(1/n)), and Logarithmic Integral (Li(X); Ei(LN(x))). |
Draws an analog clock displaying the current time. Written in Python.
Views the list of files contained in an application. For each file its size in bytes is specified. It is possible to view pictures and to delete selected files. Written in Python.
A simple clock. You can let it display in a graphical way or in terminal by modifying the variable "gui". It also offers two languages and two themes by the change of the system settings.
Transforms the current time into RGB form and displays the color as the background. You can treat it like a screensaver. Inspired by the ColourClock by Jack Hughes. The original design belongs to lookatjack.com.
A compact and elegant program that allows the customization of the soft keys in a consistent manner, whether for the global environment or for each Prime app. Now it is possible to have at any entry window your preferred characters or commands, e.g., Greek characters for scientific writing, preferred units for fast unit conversion or fast access commands with customized entry. Menus are swiftly managed with the four ways of the directional pad (left/right/up/down).
Adds key assignment to EEX to allow sto with 2 clicks. In other words, press EEX+EEX for EEX. Press Shift+EEX+EEX for ▶. Press EEX+a..z for ▶a..z (no ALPHA on needed). It also detects if a char exist before the expression/number to be wanted to store and uses Ans▶ or ▶ according to situation. When sto mode is on, ▶a..z symbol is displayed in the status bar. Additionally it works with uppercase in non-CAS mode.
An update to 
Uses the concept of 
Makes it very easy to switch between Textbook, Algebraic, and RPN with visual feedback. Also includes a pop-up version.
Makes your screen flash. Has several minor bugs but they won't affect the programs; the next version will fix these and improve the UI.
Calculates German bank holidays on the basis of Gauss's formula for Easter.
A simple toolbox for the Prime, with a screen test and other functions.
Changes the theme of the calculator.
A touchscreen keypad with support for alphabetic, numeric, and special characters. Responds to calculator color theme settings and language settings. When set to German, French, Spanish or Portuguese, a long-press on certain keys will reveal accent characters.
A numeric touchscreen keypad.
Simulates a lock screen where you must enter a pattern to unlock, similar to what Android has.
Displays the Program -> Edit -> Cmds tree without needing to edit a program. Adopt 'menuList' for your own custom menu; remove 'menuList' from the code when you want to use different menus in different apps.
Generates random colors or defined or randomly defined tone of colors by sections defined by users. You can divide the screen into something as 36*24, 4*4...with a maximum of 320*240. Please wait for updates that will allow you to touch the screen and return the displayed colors in RGB or HEX form.
Program to search inside current program text, all programs, current note text, and all notes. May have issues on the G2.
RPN Calculator app designed for typical math operations and optimized for survey calculations with angle, distance, area and volume unit support, as well as 2D/3D vectors. Converting between units is simple, and results can be stored in variables for later use. Now has a FIF menu which was inspired by the FIF49 app for HP 49/50 for working with feet-inches-fractions dimensions.
A Screen Capture utility that saves your calculator screen as a PNG file to the app's Files folder. Uses a user key definition to accomplish the task from most calculator screens. Includes a File Manager to delete and view existing screen captures.
A program to make it easy to set the auto shutoff period, using a slider. Also includes a slightly newer version without the slider.
Sudoku solving program that uses the brute force method of solving sudokus and employs recursion. Written in Python.
Manages alternate user keyboards, with 6 editable profiles to modify the functions of the calculator keys.
A simple time calculator to add or subtract time in a 24 hour clock.
Converts units between SI and the US systems.
Allows you to do unit conversions in a manner similar to the 48.
An on-screen virtual keyboard, including QWERTY and Greek layouts. Also includes a version patched to work with ROM version 13333 and a version patched to be aware of theme changes (dark vs light).
On-screen virtual keyboard, which can be called from anywhere via the user keyboard.
An on-screen touch keyboard with QWERTY option.
An on-screen virtual keyboard with a dark theme, including QWERTY and Greek layouts.
