What is Abaci?

The Abaci app perfectly uses the Fibonacci sequence to calculate the heading sizes used in print documents or digital applications. The Fibonacci sequence is a series of numbers where a number is found by adding up the two numbers before it. So starting with 0 and 1, the sequence goes 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on. Moreover the Fibonacci sequence is named after Italian mathematician Leonardo of Pisa, known as Fibonacci and his sequence has inspired design, music, books, art, and architecture and of course, appears throughout nature.
