Yup.
My Galaxy phones came with just about every app I really need. I've only added a few like a weather app and Speedtest.
Even Googling for something like "best apps" can be dangerous, as there are a lot of scammy sites out there. All I said is be sure you know exactly what you are downloading. Just look at some of the free apps on the Google Play store. Some of them are absolute crap.
I linked the stories for you earlier, so if you want you can read them, and if you feel like they don't apply to your situation, that's fine. Like I said, it's your phone and you know what you need or don't need.
I downloaded a heart rate monitor app to my two unactivated Android cheapo phones some months ago. It's Myworkouts. It was recommended by the maker of my heart rate monitor (Powr Labs), and approved by some users in Amazon reviews, so it didn't worry me. Works fine and it auto-transferred to my Galaxy.
I have maybe a dozen other apps that I've downloaded, several of them weather apps. I had a $2 weather app I LOVED on my Windows phone, Amazing Weather HD, but one day they said they were going to stop supporting it because "Windows Phone is not the stallion it once was." When the date arrived, it stopped working! I was SO SAD! It was fantastic. It had a mode where it showed approaching rain, a radar overview, basically. You could zoom in, zoom out, and believe it or not I could zoom down so far I could see my house! In detail! Of course, you could do that anywhere, AFAIK, on the planet! Guess it used Google Maps or something. Obviously, satellite imagery. I haven't found anything like it on Android... yet. A guy showed me something like that on his iPhone some years ago (approaching weather, very impressive and graphic), I guess that's where I got the idea.
I'll try to run with that idea that practically everything I'm going to want/need is already on my Galaxy! Well, I'm told that there will be ROMs or something, customisations coming out that I should maybe check out.
