Having an app on the Apple App Store gives you multiple dofollow backlinks to your homepage, support page and privacy policy at the bottom of the Information section.
Though your cannot control the anchors, this is probably one of the highest DR backlinks you can get. You will however need to have a real app on the store and the review process can be quite picky, and you need to pay the Apple Developer Program membership fee but it's definitely worth it.
Here's an example of a backlink from apple.com:
https://apps.apple.com/us/app/runwayml/id1665024375This link is dofollow with domain authority of 97 but you cannot control the anchor. You can get this backlink for $99/year. This backlink is requires some hard work to obtain.
