How do I upgrade?

Trac-King was built by Expats for Expats and it is a self funded start-up, so we would like to thank for your support and we're very grateful for your one off In-App Purchase of US$9.99 to use the App indefinitely.

If you are using Trac-King for Expat Tax purposes, we hope you'll agree, it's a small price for the convenience it offers.

You can initiate the In-App Purchase at anytime from the Setting screen, or by touching the 'Date-Range' scroller at the top of the History Screen.
