Thanks to the Amazon Free App of the Day promotion on the Amazon Appstore for Android, Knots 3D is not only the #1 downloaded reference app, it is also the #1 downloaded free app overall! We are very excited about the attention this promotion is giving Knots 3D. The many 4 and 5 star reviews the app has generated are very encouraging and certainly motivate us to keep adding knots and making the app better and better! Thank you all who have taken the time to leave positive, constructive feedback.
