BUG FIX SUBMITTED, PENDING APPLE REVIEW: v2.9.1 of Knots 3D was released to the iTunes store 10/9/12 with updates for iOS6 and the new 4″ display on the iPhone 5. Unfortunately it introduced a minor bug on older devices with smaller screens where the last row of the knot list is not reachable or displayed, e.g. Zeppelin Bend. This bug has been fixed and submitted to Apple. We expect it to be approved and available on or around 10/18. Thanks for your patience and understanding.
