Choice design and mental model
Yahoo Digest mobile app is a simple and easy to use. It has limits on the numbers of news by providing only 10 news stories in one page to help users read the news more comfortably with digestible chunks of texts. It also publishes news twice a day, which is the same metaphor like reading newspapers in morning and evening.
In addition, every reading experience collects one little circle dot to complete the big circle. It not only provides feedback to user but nudges them to stay on this news app longer and come back more often.
Unclear visual affordance
However, some elements in Yahoo Digest would be better to be fixed. There is a button on the main page which looks like hamburger menu button. Initially I thought that the button was of the page menu, but it turned out to be not. It was actually for checking the list of past news stories though the graphic interpretation made me confused.
Also, the icons are not really clear if they are clickable or just information. With too much neutralization of UI colors, icons seems to lose their original functions. Users need to read many icons on a article as they are not easily discernable with same colors and styles. In addition, the feedback on UI to let users know is not clear enough. Currently, the background color of the number on an article changes if a user has read it. It is too natural and subtle change to notice and the feedback of UI does not represent ‘have read’. Instead, ‘check’ or other UI elements would be easier for users to understand that they have read the articles.
Loose context in UI
In the news collection circles which shows the article numbers you’ve read. Right next to those circles, there is a calendar button which looks like it is going to show the articles of what I have read and haven’t. However, it is not and the function of the UI is not really clear and not easily understandable. To see what I haven’t read, I had to click the hamburger menu button which has no connection in terms of context. Also, the colors are loosely linked with the information. Sky blue color does not represent ‘America’, purple does not show any relevance with ‘Europe’ and other colors as well. Rather, it would be better to use the colors where they are really needed like the issues of neutralized icon colors mentioned above.
Deep hierarchy of UI
After clicking the hamburger menu button, it shows a few buttons again. Setting button is one of those and if this button is clicked, a new layer of menu comes up on top of hamburger menu page which is not a really common case. It can make users lost on their ways with deep and unclear path of the information architecture on the app.
