Setapp is approaching developers to participate in alternate App Store which it expects it will be able to run following Digital Millennium Act (DMA) approval in EU.
While it is still not clear, if Apple will have to follow DMA rules on opening platform for alternate App Stores, companies are now trying to get developers onboard.
Setapp promises 90% revenue share with developers. Apple pays 85% to developers eligible for App Store Small Business program (developer should make less than $1 million on App Store sales) while also providing access to all world markets.
