Mac: If you're an avid Mac productivity app user, you know the cost of buying software can get a little out of control. Setapp, which was previously in beta, is a $US10 ($13)/month subscription service that gets you access to 61 different Mac apps.
The usefulness of a service like this depends on a lot of things, but it seems most helpful when you need to use particular software in short spurts, say, on a project-by-project basis. To that end, Setapp makes the most sense as something you'd turn on and off throughout the year. Of course, others might find it useful year-round, and no matter how you look at it, there's some good stuff included here, like Alternote, Forecast Bar, Gemini, Lacona and Ulysses. You can give it a shot for free for a month by signing up now.
