If you’re looking for a Google Reader client for iPhone or iPad instead of using Google’s web interface, the consensus seems to be that Reeder is the best choice. While it’s a very good choice, I don’t necessarily agree that it’s the best choice.
Personally, I think Byline is a better reader for a few crucial reasons that I’ll lay out below.
iPhone version
In a word: speed.
Both Reeder and Byline cache images when synchronizing to speed up their display, but Byline is significantly faster at displaying cached content than Reeder is. Beyond that, Byline also caches web content when it detects that the full article is not available, or if you explicitly set it to cache web content from a particular feed. While I like and miss Reeder’s Readability function, I find the offline caching of full web pages more useful to me — not just for use offline, but for making navigation faster.
iPad
Everything above about speed on the iPhone version holds true on the iPad. I don’t understand why Reeder is so slow at rendering images that are already in its cache; sometimes it’s so slow it makes me wonder whether the cache is actually working properly.
But more importantly, on the iPad my biggest complaint is text contrast. While I love the control Reeder gives me over font size and I prefer the line spacing it uses to Byline’s, the text in Byline is black on a white background, instead of dark grey on a light grey but textured background. My eyes get tired out very quickly using Reeder, even at larger font sizes. And the dots in the texture of the background are simply distracting.
Gestures
Another speed-related advantage Byline has over Reeder is the gesture it uses to move between articles. In Reeder, you have to either use the admittedly well-placed up and down buttons on the left side, or you have to pull down at the end of an article to display the next one. Swiping left and right are dedicated to other, less important tasks. In Byline, you move between articles by swiping left and right. It’s a smaller, easier gesture to complete than pulling down at the bottom of an article, and it doesn’t require that you actually be at the bottom of the article to do it, making quickly scanning a breeze.
If getting through your feeds quickly and efficiently is important to you, Byline is a clear winner over Reeder.
