Instapaper lets you save links to read later, and it does exactly the same thing on Android, but the actual developer is different from the original app. Not having the time to focus on the Android version of the app, Instapaper creator Marco Arment turned it into the hands of Mobelux (which also created Tumblr for Android).
While the app does its best to mimic the iOS version, there are several key differences; most notably, it lacks a full screen reading option and pagination - an omission already noted in several reviews of the app over at Google play.
The price is a bit lower, though. On iTunes, Instapaper costs $4.99, while the price for the Android version is $2.99.
