LifeCodex is an iPad app that functions as a UI wrapper for an SQLite database which contains tables of Life Objects and Glider Constructions.

The basic version has all known stable object up to 18 Bits, and all oscillators and spaceships up to 30 Bits in size. There are also about 3500 Glider constructions based upon these objects.

Each object record contains the SOF, WCode, and RLE bit encoding representations, as well as a symmetry code. Oscillators also contain the Hickerson Rotor Descriptor. The UI provides a way to search the database based on any of these characteristics. Some objects contain a name, or discoverer. (Although at some point I stopped trying to figure out who the discoverer might be because it was more work that I wanted to put into it.)

The construction database has several parts. In addition to the constructions, there are tables containing more generic “components”. These in turn contain individual Glider constructions that use the component to construct new objects.

The app supports copying and pasting into Golly.

(Note: The app will run on smaller screens, but no guarantee as to the appearance or usability.)

This app does not collect, record or transmit any user information or data (including analytics) to any webserver. The objects and patterns are public domain. No claim of ownership or copywrite is made.
