DragThing Help | About

TLA Systems Ltd. is a software company based in Glasgow, Scotland that has been developing world class Macintosh software since 1992. We are best known for DragThing, the premier application dock for the Macintosh, and PCalc, the veteran scientific calculator.

We became a limited company in 1998 and are dedicated to producing the highest quality Macintosh software at an affordable price. Because our software is distributed and sold directly to the customer over the Internet, we can keep our overheads low and reinvest the savings into our business to make more great products.
