Best Reddit clients for Android
Relay for Reddit
Snappy, user-friendly Material Design interface with a plethora of features like multi-user support, themes (including a night mode that goes easy on your eyes in low-light environment), easy switching between comments and links, and many, many other. One of the highlights is the gesture-based UI, which is a big selling point. Relay is currently among the more popular Reddit clients for Android, and rightly so. It's available in a free (ad-supported) and paid versions.
Sync for Reddit
Another quite popular Reddit client, Sync for Reddit (formerly known as Reddit Sync), also comes with a beautiful and customizable Material Design layout, messaging support, a gallery that supports GIF, Gfycat, and GIFV images, an advanced submission editor (an important feature for those redditors that like to contribute to the site). The free version comes with ads, but the paid one doesn't.
For a long time, BaconReader has been one of the go-to choices when it comes to browsing Reddit on the go. What separates it from the rest? BaconReader is often lauded as one of the more intuitive and easier to use Reddit apps. It also comes with a "Redditorial" (Reddit tutorial) guide that will you show you the ropes of making full use of Reddit, a nice feature for novice users. It also comes with a fullscreen mode aimed at tablet users.
Reddit is fun
Reddit is fun, indeed, yet the eponymous Android app has a few issues. First of all, it doesn't natively support the images and GIFs hosted on Reddit: you'll have to get content with Android's built-in WebView feature. Apart from this, it's pretty straightforward Reddit client that comes with Material Design to some extent, as well as different themes (dark, light, pitch black by default, others can be downloaded as well). It's also the only Reddit app to support Synccit and browse your Reddit history on any supported device.
Now for Reddit
Another popular Android app for Reddit is Now for Reddit. It comes with a card-based interface layout that makes browsing pretty useful - you can browse your subreddits by swiping left or right, full theme support, and native link support for WebView, YouTube, Imgur, and Gfycat. You can also watch videos thanks to the baked-in support for Reddit TV.
