In one of his interviews he said he wasn’t very interested at the moment. But he did say he will watch Lemmy and the fediverse to see the growth of it and decide later on if it’s worth it to build an app for Lemmy. He isn’t sure if Lemmy will actually grow after July 1st but time will tell.
Mlem and Memmy are in the works for iOS as well and these apps seem promising. So much better than using Lemmy in a mobile browser.
