Preview release on Android

Iotic Fractal and Iotic Trikona are now available on Google Play as preview releases. To install:

  1. Visit our announcement-only Google Group driota and click Join the group. If you don't see that option, sign in first with the same Google account you use on Google Play.
  2. Fantastic Fractals, app name Iotic Fractal: Opt in to become a tester, and then Install Fantastic Fractals (free) from Google Play.
  3. Triangular Geometry, app name Iotic Trikona: Opt in to become a tester, and then Install Triangular Geometry (free 5/17/2026 to 5/30/2026) from Google Play.

The driota group carries announcements of major app releases only — very low volume, no spam. Already in the broader testers-community Google Group? That works as well.
