Blisk is a fantastic tool.
I had no prior expertise with formal app evaluation and testing and was able to use Blisk right away, straight out of the box.

The software includes a detailed "Getting Started Guide" as well as "video tutorials" that explain all you need to know. Redeeming and installing the app is simple, and I had no issues. You install a desktop version on your laptop and off you go.

After installing Blisk I reviewed our newly designed website and was quite impressed by the side-by-side comparison Blisk offers.

I reviewed an iPhone, a laptop, and an Android phone side by side. It is incredibly powerful to see the tested app on multiple devices at the same time and immediately see where the issues are.

During the review, you can snap screenshots of issue areas and annotate them using the built-in tools. You may also record a video screencast of your evaluation and share it with your colleagues for comment or bug fixing (or both :-)).

Blisk is pretty impressive and I am happy that I grabbed it on time.
I am very pleased with the software and can only recommend it, even to complete novices.

Grab it as long as it is still available.
