Quiky (Quick Wiki) is a simple, easy to use and clever personal offline wiki for your iPhone and iPod Touch.
Each wiki consists of several pages with contents, which can be formatted using markup language (similar to Wikipedias).
Quiky offers automatic "distraction free" layout, when editing page in landscape mode, to offer as much visible contents as possible. Also auto-save is triggered after 5 sec of inactivity plus on each new line, so you never lose your edits.
Wikis are available for download to / upload from a desktop app via iTunes File Share feature.
Theres no limit for wikis or pages, except for your devices available memory.
