Power On Software has announced Now Up-to-Date & Now Contact 4 is Mac OS X native.

The update to the personal-information manager - announced at Macworld Expo, San Francisco - incorporates Mac OX's appearance and allows emails to be turned into notes, appointments and to-do items.

Power On has also added an HTML-based help system, greater customization of category and event colours, and Memo - which syncs with Palm OS personal digital-assistants.

Clent Richardson, Apple's vice president of worldwide developer relations, said: "Power On Software's new version of Now Up-to-Date & Contact is an excellent example of a Macintosh application taking advantage of all that Mac OS X has to offer."

Now Up-to-Date & Contact 4 costs $99.95 from Power On's Web site. An upgrade is available for $39.95.
