NewsBrain (US$4.99) is a new app to deliver news you are interested in and present it on your iOS device. The app learns from your likes and dislikes, which you can register on a sliding scale that includes degrees of attraction, neutrality or repellency.
You log in using a Google, Twitter or WordPress account. Articles are sourced through Feedly. Once the app learns your interest, it gets pretty good at predicting other articles that meet your criteria.
"NewsBrain learns your interests using a unique neural technology. There's no need to wade through the internet looking for interesting things to read, since NewsBrain finds it for you. It starts out as a general interest magazine, but as you flip through pages, read articles and indicate which ones interest or disinterest you, it quickly customizes itself and becomes a highly personalized magazine geared to your specific interests and tastes," according to Mike O'Connor, the developer of the software.
I spent some time with the app, and found that after a while it did figure out what I was and was not interested in. The GUI seems a bit overwhelmed by the information, and it is a bit too busy to quickly comprehend an article. Sometimes text is overlaid on a graphic, making things a bit hard to read.
