I’m not sure if the iPhone 8 has this, but the latter models do have a long exposure setting that does exactly that. It’s a submenu under Live Photo, after taking the shot you swipe the resulting photo up and you have a series of exposures. The one on the far left is “Long Exposure”. Works well with moving water.
Yes, my phone has that feature. It works okay but isn't as versatile as using the Slow Shutter app. Here is a link that shows you all the features of the app. The app is fun to play with.
