To use Lothar, you enter a number into the edit box using the keypad provided and then hit the next to precede through successive values in the Collatz numeric sequence. To follow the sequence in reverse, activate the reverse switch and click the previous button through successive iterations. Occasionally, when viewing the previous numeric values in the Collatz sequence, a multiply button will appear. Where as normally this number could have been arrived at by taking an odd number, multiplying by 3 and adding 1, it’s also possible that number was arrived at by dividing some number by 2. By default, previous always selects the first option; select multiply to select the second.
Clicking on the ⓘ will take you to the about screen where you can learn more about the Collatz algorithm and about the man who first described it, Lothar Collatz. The about page is a built-in web browser with forward, back and reload buttons. When a page is loading, the reload button becomes as stop button to stop the action. There is also a home button to take you back to the original about screen. Note the about page is stored within the application and does not need to use the Internet to retrieve data. However, clicking links on the about page will load external data to the applications web browser.
