Pros

  • Free, can run from anywhere

Cons

  • You may have trouble getting help

Bottom Line

At any rate, the fact that it doesn't install means that it can run from anywhere, even an external hard drive... so if you've got one file with important information that is for your eyes only, you can make it vanish with Safe Calculator.

Would you buy this?

Safe Calculator is a neat little utility that pretends to be the basic Windows calculator when you launch it. In actuality, it's a safe that can take a single file and encrypt it, disappearing it into the application itself.

The tiny, free Safe Calculator utility would be useful on the go or when sharing a public computer, when you need to write something down and then hide it.

It's a good thing that Safe Calculator is a simple program, because you may have trouble getting any help using it. We found the feedback form at the app's native website, www.krilome.com, frequently unresponsive. For that matter, the site in its entirety went up and down during our testing period.

As for Safe Calculator itself, it's easy as pie. It doesn't even require installation. All you do is enter the password at any time and click MS, and "safe mode" appears, changing all the calculator buttons to ones that would be useful for an app like this. Then, click on + to store and = to confirm. After that, you can execute the file, bring it back from hiding, or delete it.

It's difficult to figure out why developer Krilome decided to make the utility look like the Windows calculator when not in use, since when you're in "safe mode", the buttons change anyway and it doesn't look anything like a calculator. Why not make a safe app that looks like a safe, instead? Do you really need that extra level of subterfuge?

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
