Whenever I go through the features of a mobile app that involves consumption of text e.g. web browser, email client, or document reader, once I come across a statement that says there’s no text reflow, I forget about the app immediately. Text reflow is the ability to the ability of text to wrap, or adjust, itself to an allotted space, especially when the user zooms in on content. Because of the limited size of mobile phone displays, I consider it an essential.
Without text reflow, the user has to side scroll line after line. Here is an example of what text looks like on a mobile screen when there is no text reflow:
Painful. Irritating. Time-consuming. This is 2014. As such, in my books, web browsers and email clients that do not support text reflow are an automatic fail. Nobody should be creating any mobile app that does not reflow text any more. That is so 2009.
