Reddit, the most diverse free forum around. Now mobile.
Reddit: The Official App is a bit of a funny title, but it fits. Prior to now, Reddit had a fantastic mobile interface accessible by browsers and a matching mobile app, but with its latest moniker, the Reddit app has become a great thing all to its own. It provides compact and easy-to-use access to forums from r/showerthoughts to r/cats to r/grilledcheese. And of course, it does this all for free.
Perfectly-made and fully featured
There's not many features a forum app needs to work well, overall. Reddit: The Official App allows you to browse and navigate the various smaller forums (subreddits) of Reddit easily. A lot of care has been made to make image-viewing easier on mobile, though!
User experience might vary, but it'll always be decent
Overall, how much you get out of Reddit: The Official App depends on how much you use Reddit. If you're a frequent poster, collecting karma and participating in discussions, you'll love it. If you browse Reddit for cat pictures and funny stories, you'll like it. If you're not a fan of how brusque some of the users can be, you can safely take a pass on this app. But if you have any reason to browse Reddit, that reason's good enough to consider downloading this app.
