Slide is a great, open source app that works on Android and IOS for reddit just fine. You don't have to use the reddit site or app if you don't want to. But it's fine to skip it too I suppose. I just find it far superior to other social media like twitter, facebook, and instagram. It certainly has it's warts but it is quite easy to simply choose your subset of forums and ignore everything else.

The third party apps are very good though, some even open source.
