Aman is right, a lot of "routers" can do both. The crazy thing is that app routing and LB are often used together. The routing gets you to the right LB, basically, in much the same way as the ingress controller in a K8s deployment gets you to the right service. If the setup uses HTTP headers - host, URI, cookies - to make a decision, that's operating at L7.
Without diving in too deep, there are a variety of different models that combine the two. For example (disclaimer: I work for F5) the BIG-IP has a "Fast L7 Mode" which makes decisions based on limited L7. That kind of mode is great for performance and for stateless services where you don't need deeper inspection. Virtual hosting and microservices (again, especially in container environs) is a good place to use a combination like that.
