Oleksandr Kosovan, the CEO of MacPaw, sharing the news that CleanMyMac X is now on the Mac App Store:
In 2018, CleanMyMac X switched to a subscription model — a ubiquitous way of getting apps on the Mac App Store. The same year (2018), Apple significantly improved the store itself with a new design and curated content. The fact that the Mac App Store became much better and that it supported subscriptions, made us work on building CleanMyMac X for the Mac App Store.
As you would imagine, there are some differences between the App Store and non-App Store version, but if you prefer the App Store for purchasing Mac apps, this is good news.
