Apple AppStore Link

Open, edit, and save TiddlyWiki single file wikis on iOS.

Works with files stored in any files Location available on iOS, including files Locations provided by cloud services.

I use it with git via Working Copy to work with my FoodWiki.

The name is from the computing term:

A quine is a computer program that takes no input and produces a copy of its own source code as its only output. The standard terms for these programs in the computability theoryand computer science literature are "self-replicating programs", "self-reproducing programs", and "self-copying programs". Wikipedia

TiddlyWiki itself is a quine.
