Is there a service for delayed posting on Instagram with the ability to send to fb, ok and vk?

Question

SMM

Actually the question is in the title. When creating a post manually, you can check the checkboxes in which networks to share the post. But I didn’t find it in any application for PC or auto-posting service on Instagram.
Of course, I would like a free option in the first place, or with a one-time purchase.
