Canadian developer Coradine has released LogTen Pro and LogTen Express, applications designed for pilots who want to keep their logbooks on Mac OS X. Their smart filtering feature allows pilots to choose among only the information they need, such as aircraft specifics, departure and arrival times and more. The Pro version adds the ability to keep track of such information as operating capacities, on and off times, flight numbers and more. LogTen Pro also conforms to international regulations and offers support for unlimited logs, data import and export and more. LogTen Express sells for US$39 and the Pro version is $89. Both applications require Mac OS X v10.3 and a G3 processor running at 500MHz.
