Reminiscent of the DSOrganize homebrew for the Nintendo DS, this is certainly an essential for any fx-CG50 owner. The only issue I've encountered is its image viewing abilities, which could be improved. Still, when you can read a book, use 2FA, or even keep track of your savings on your [b]calculator[/b], the pros outshine the single con.

Amazing program - a must have for anyone who uses a cg50. Wide range of features that means not having your phone with you (e.g. at school) doesn't matter.

One bug: In the tasks section, sometimes when you switch the tasks the whole calculator crashes and you are forced to press the restart button.

This program works on my CASIO fx-CG50 for the most part as it was intended. The function key color setting, a setting that I believe allows you to change the function key colors on the screen, is the only thing I have noticed to not be working on my CG50. Its features are mostly useless to anyone who owns a cell phone though, except for the power functions which can help save battery life.

This app is a must-have for any Prizm owner. All functionality (like clock, timer, stopwatch, in-depth power settings, calendar/task/event manager, authenticator, virtual wallet, random password generator, flashlight mode, full-featured file manager, picture viewer, add-in manager, system info, and password lock). These are all features I could find, there could be some others. Either way, its must-have for Prizm.
