Is a guy serious about dating you if he still checks his dating profile every day?

Anonymous
So I met a guy online and have hung out with him every day for a 9 days now, and we have been intimate also (every day since our 3rd date). It already seems like we have known each other for a while, and he told me he wants a comitted relationship. I know everything is fresh and new so I dont expect him to stop looking or dating, but... well, the other day, he was showing me a video on his phone, and I couldn't help but notice at the top of his phone were notification icons from 4 different dating websites. I disabled my profile by then, but it made me curious. So I reenabled my profile and checked after a couple dates (we see each other for at least 4 hours at a time) and he got online as soon as i left each time. I gave up checking after two days and disabled my profile again because it just felt like spying and I dont want to jump to conclusions or bring it up with him because it's way too early for that. But when we hang out, his phone pings every 5 minutes and he always gives it a quick check. I really like him and I don't want to ruin anything... I guess I'm just wondering if this means maybe he is not as into me as I am into him? Or is it normal for guys to keep browsing for a while? Thanks for everyone's responses and help I appreciate it.

I just want to thank everyone for their kind and understanding responses. I spoke to him a bit today and he told me he is talking to 2 other girls and that he is still active on multiple dating sites. I was happy that he is being honest with me, but still I wonder if this means I am not exactly what he is looking for since he's still dating others. He says I am the most serious one, though, since we have hung out every. Any thoughts? Thank y'all again for your help
