Figured I'd leave my vote for Redreader here. It's open source, works offline (has a fully featured cached versions system) and I've used it for years. It also supports custom tabs too, so if you use a decent browser with add-on support (Firefox) you can get ad-blocking working for all articles you read within the app.

Apollo on iOS is fast and easy. Would recommend to anyone.

Apollo, FTW. It has my vote. Grabbing content to quote is still a problem (it sits beneath the bottom bar, probably a negative padding issue), but otherwise I have no complaints.

Sync for Reddit is one of the best out there. Very customizable and the developer is very responsive and open to suggestions.

Reddit is fun on Android is so much better than official reddit one.

For which its become pretty much the exclusive way I use reddit now. I can't remember the last time I opened reddit on anything other than my phone.

It's actually clean, and configurable enough that I can set the right information density for myself, and I dont get all the banners and ads bugging you to use reddit's official mobile app. Plus an actually consistent dark theme is a massive bonus.
