Does this mean he’s not interested anymore?

I matched with this guy on tinder the other day and we talked all day. He was responding to me pretty much right away even if I took awhile to respond back to him. We talked pretty much all day Thursday and Friday but not much at all yesterday and I haven’t heard from him today. He seemed very interested the first two days and even saved some pictures of me the other day. He had asked me a question last night and I responded but he didn’t say anything back.
