Hi Nicholas,
I recently bought your app. Its awesome. Great work!
I'd just add that there are couple of things you could do to improve:
1. On sites like 'The Verge', half article is posted with note 'Developing'. But even when the full article is posted, the Read article shows only that half article.
2. Please include a night mode. AMOLEDs tend to burn eyes in low light, specially with white background. What I'd recommend is to add a mode that reads the phone time and at 7pm (the user specified night time), starts toning down the articles background and text brightness. Note: Gray text on black looks more awesome than white text on gray or navy blue. (You can also make a slider control for this)
3. Please show the full article when an article is touched upon.. i.e. kill the 'Read Article' from article options. When a new article is clicked upon, you can start loading the rest of the article. In that case, you can compare the two text and replace it from the point it the article differs. Usually, the replacing point is ".... (continue reading)". Replace this with the rest of the article.
4. Please add an 'Open Media' or 'Open Video' button in the article options. This would enable watching any video attached to the article.
Also, Al_2 has posted excellent points above for formatting.
