AllTrails has, I think, seen this coming and offers their sub as part of a larger package that includes some other, related apps.
I’ve used AllTrails for 10+ years and they’ve degraded by trying to force into paid subscriptions for basic functions. So I use them less and less (I just want maps and tracking hikes). So I’m happy that Apple is adding them and I don’t think will make me use AllTrails any less.
