SMITH MICRO SHIPS CHECKIT REPAIR & PERFORMANCE SUITE – A COMPLETE SOLUTION
TO KEEP YOUR MAC IN PEAK FORM

Industrial Strength Diagnostic, Cleaning, and Repair Tools Combined with
Flexible Intuitive Backups Provides a Complete Mac Maintenance Solution

San Francisco, CA – January 10, 2006 — Smith Micro Software, Inc’s
(NASDAQ: SMSI) Allume Systems Division, today introduced the CheckIt Repair
and Performance Suite at MacWorld San Francisco (Booth 1237). The CheckIt
Repair and Performance Suite brings three leading utilities together in one
package: SpringCleaning a powerful “Uninstaller” and cleanup utility
designed to help users rid their computer of unnecessary and redundant
files; TechTool Platinum, a full featured version of Micromat, Inc.’s
leading diagnostic and repair tool; and EMC Dantz Retrospect Express,
flexible and intuitive personal backup and restore software. CheckIt Repair
and Performance Suite is the perfect solution for those who can’t afford to
loose important files or the down-time associated with hardware problems
and want to maintain their Mac at peak performance while ensuring that
their critical files are backed up and protected.

“With powerful new features including the ability to gather photos and
music files, folder synchronization, Widget Finder, and other features,
CheckIt Repair & Performance helps take the guesswork out of managing files
on your Macintosh,” said Pauline Shumake, Smith Micro’s Senior Product
Manager. “When it comes to locating and collecting media files, or removing
outdated, orphaned, or redundant files, there is no tool out there more
powerful than this latest version of SpringCleaning.”

“TechTool Platinum truly is the next generation disk utility for the
Macintosh. Whether you’re looking to optimize a drive, repair its directory
structure, recover lost or trashed files, or just the peace of mind of
knowing your drive is in good shape, TechTool Platinum is the tool to reach
for,” said Christian Pickman, Micromat Incorporated Product Manager. “Our
eDrive feature means you can recover from many problems without carrying
around a bunch of CD’s.”

“EMC Dantz Retrospect Express complements the other utilities in Allume’s
new suite because it gives users a powerful and flexible tool to protect
their files,” said Larry Zulch, Vice President and General Manager, EMC
Dantz, EMC Corporation.

“By bringing these three tools together in a single package at a fabulous
price, what I hope to bring the user is greater peace of mind,” said David
Polzine, CheckIt Product Manager at Smith Micro. “This is the solution to
reach for when things go wrong on your Mac.”
