Yup. (Not that Apple really cares that much about it for their own software… But it’s there for developers to take advantage)
Developers can add an identity check if they want, though. The way that identity check works is, the app itself (not the Mac App Store App) sees if it’s got authorization to run. If it doesn’t, it asks for your Apple ID and password and then verifies that information with Apple. Once it gets the OK from Apple’s servers, it saves that authorization and continues running.
This is not a fact, it’s your observation. Not a single professional DAW or notation program aside from Logic is available in the apple app store.
Yet. Small indie companies (ie. Pixelmator) are making millions supplanting the old stogies, and it’s only a matter of time before the old guys need to adapt or die. And among professionals even, the fallout from the latest iLok debacle proves that customers are no longer happy with the status quo.
Steinberg is not a new developer. A young guy just starting out might find 30% commission reasonable, but a company like SB, owned by Yamaha, already has established distribution channels. They offer refunds to unhappy customers, which the Apple app store does not, and they communicate with the users, which Apple does not.
A “large” company like Steinberg has lots of overhead costs associated with organizing distribution models. There’s also a lot of investment in maintaining copy protection. Would you rather have them spend their time figuring out dongle issues and managing server status/bandwidth for each release, or would you rather they focus more resources on improving the actual software we love to use?
Yes, you can get refunds on Apple App store software.
Having an app on the Apple App store does note mean you lose the right to communicate with your customers, either.
Despite being under the Apple banner, Logic does not have a reputation for being the best, most reliable DAW. However, it IS the most affordable, easiest to buy and install DAW on the platform. Although I don’t suggest Steinberg try and play a price war with Logic (no need: Cubase has a solid rep), not having a “BUY” button for Cubase on the App store means lots of lost sales for Steinberg… and continued frustration for those of us shackled to the little plastic dongle…
