APP file extension - Cybiko computer application file
What is app file? How to open app files?
File type specification:
The app file extension was also used in Cybiko devices.
The Cybiko is a hand held computer introduced in May 2000 designed for teenagers, featuring its own two-way radio text messaging system.
It has over 430 "official" freeware games and applications. Because of the text messaging system, it features a QWERTY Keyboard that was used with a stylus.
An MP3 player add-on was made for the unit as well as a SmartMedia card reader. The company stopped manufacturing the units after two product versions and only a few years on the market. However, because of the unique radio messaging hardware there is still a hobbyist community using Cybiko.
This app file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
