It’s getting hot out there. But it’s still nowhere near as hot as the new deals coming into the Cult of Mac Store. This week we’ve added an app that’ll change how you work with PDFs, and a set of future-ready Bluetooth earbuds. There’s also a comprehensive set of courses in Apple’s Swift coding language, and an app that turns your phone into a mindfulness tool. Most are discounted by half or more, read on for more details:

Here we go again, sharing our favorites from the week’s deals on gadgets and lessons. This round we’ve got a massive expansion for iOS storage, a powerful PDF flipbook maker, and comprehensive lessons in coding and Microsoft Office.

Take a look:

You can now share PDF documents with friends and colleagues using the WhatsApp web client in your browser. The feature was previously only available on mobile, and inside WhatsApp’s new desktop app for Mac and PC.

There are times when you need to sign a contract or other document that comes over via email. You could print it out, sign with a pen, and then scan it back to the recipient, of course, but that takes forever. Might as well fax it.

If you get a PDF form via the Mail app on your iPhone, however, you can sign it right there on your little pocket computer using just your finger, and then mail it back, all without ever committing ink to paper.

Here’s how.

Readdle’s highly praised iOS app PDF Expert has landed on the Mac. Shortly after its debut, it shot straight to the number one spot for paid apps on the Mac App Store. Apple’s own Preview app works fine for simply reading through PDF files or making tiny edits, but people who work with PDF files more frequently and need more power can benefit from giving the $19.99 PDF Expert a chance. Cult of Mac got the opportunity to do just that.

Everybody knows that the leader in the category of PDF editors and readers is Adobe with its Reader and Acrobat apps, but the latter costs $14.99 per month for a subscription or a staggering $449 for the full desktop software. As long as you don’t need to create PDFs, PDF Expert only asks for $20 out of your pocket and it’s jam-packed with all of the necessities and then some.

I’m a big fan of getting instructions off the internet: recipes, directions on car maintenance, or video game walkthroughs, for example. The problem is that you need to be online to view them.

Now in iOS 9, however, there’s a way to save web pages to a handy, offline-friendly PDF file. The next time you’re flying on an airplane and trying to get through Broken Age with a walkthrough, you’ll be in luck.

Here’s how to convert any webpage in iOS 9’s mobile Safari to a PDF and then read it in (or send it from) iBooks.

So a good Halloween costume idea is not coming to you. Steve and Marianne Wintercroft can get you started with an alluring mask.

The British design couple has made a company out of designing masks that the buyers build themselves. For a few bucks, you can download a template of a polygon constructed animal head that you print, cut and assemble.

PDFs are convenient and used by almost everybody, but flipping between preview windows is not a very attractive or engaging way to view content. Flip PDF for Mac makes it easy to create beautiful digital books and presentations out of your PDFs, perfect for designers, photographers, advertisers, anyone who could benefit from a beautiful digital presentation of their work. And right now, you can get a copy for a tenth of the normal price, just $9.

Times are moving fast, and keeping up can be tough. That’s why we’ve gathered some great ways to step up your game without feeling the pain in your wallet. From comprehensive coding courses to gadget self-repair and sci fi-worthy lightbulbs, we’ve got something to take anybody to the next level. But act fast — like the present moment, these deals will be gone before you know it.
