What's New

Silverback 3.0

After much anticipation we’re pleased to say that the new version of Silverback — the most popular usability testing application for the Mac — is now available to download on the App Store.

As the App Store doesn’t allow for upgrade pricing, we’re offering everybody the "upgrade price"of $39.99 or £29.99. This will go up to the full price of $79.99 or £59.99 on the 17th July, so it’s worth grabbing your copy now.

What’s new?

Silverback 3 has been redesigned and rebuilt from the ground up to take advantage of the latest Apple hardware and software. It’s now faster and more powerful than ever before.

We’ve listened to your feedback and added a number of great new features, including the ability to define user tasks and add/edit highlights before export. We’ve also created a FREE iPhone helper app so you can add your observations on the fly.

Silverback 2.0

The existing version of Silverback 2 will remain available as a FREE and unsupported shareware product. So we hope it will give you many happy hours of testing.
