i.a.T.Viewer

i.a.T. Viewer is the free, read-only companion to i.a.T. Creator, letting you open and explore Interactive Argument Tree (.iat) files anywhere with no internet connection required.
First, build your argument tree in i.a.T. Creator on your Mac or PC, or download any argument trees you are interested in from https://ia-tree.com. i.a.T. Viewer opens your .iat files directly on your iPhone or iPad, so you can review, study, and navigate complex argument structures whenever and wherever you need them. Whether you are on a flight, in a meeting, during a debate or find yourself in an impromptu conversation, anywhere with or without a signal, all the facts and media for your argument tree will be available at your fingertips instantly.
The app also displays a Numerical Assessment and a Tiers View — the former a parameterized Bayesian maths assessment of the arguments, while the latter is a Tiers comparison of products or candidates' merits.
Key features:
Fully offline — works with zero internet connection, always.
Opens native .iat files exported from i.a.T. Creator
Free, with no account, sign-up, or subscription required
Lightweight, standalone viewing experience for reading and exploring argument trees on the go.
