Mobivention is a different company than MacPaw, who already has SetApp for the Mac and a limited set of iOS apps. MacPaw is using Apple's new terms to create a
bundle of apps for a monthly subscription via
SetApp. I use it on the Mac because it's cheaper than buying/subscribing to apps I regularly use. It will be interesting to see which apps will be in the iOS bundle and pricing.
While news outlets are calling it an alternative app store, SetApp is not a store but simply a subscription service that grants access to a set of apps; much like say Apple News gives you access to a variety of news outlets and magazines.
