The Top Ten Reasons Why Apple Rejects Apps

For those folks developing library apps:

The Top Ten Reasons Why Apple Rejects Apps

“Some of the mystery behind Apple’s app rejection decisions has been solved. Now, the powers-that-be behind the App Store have finally revealed why software is so often rejected. You might be surprised by how mundane its reason are.

Apple’s new Common App Rejections page explains the top ten reasons why apps were rejected at the end of August 2014. Here’s the run-down:

14% : More information needed

8% : Guideline 2.2: Apps that exhibit bugs will be rejected

6%: Did not comply with terms in the Developer Program License Agreement

6% : Guideline 10.6: Apple and our customers place a high value on simple, refined, creative, well thought through interfaces. They take more work but are worth it. Apple sets a high bar. If your user interface is complex or less than very good, it may be rejected

5%: Guideline 3.3: Apps with names, descriptions, or screenshots not relevant to the App content and functionality will be rejected

5%: Guideline 22.2: Apps that contain false, fraudulent or misleading representations or use names or icons similar to other Apps will be rejected

4%: Guideline 3.4: App names in iTunes Connect and as displayed on a device should be similar, so as not to cause confusion

4%: Guideline 3.2: Apps with placeholder text will be rejected

3%: Guideline 3.8: Developers are responsible for assigning appropriate ratings to their Apps. Inappropriate ratings may be changed/deleted by Apple

2%: Guideline 2.9: Apps that are “beta”, “demo”, “trial”, or “test” versions will be rejected

The page also provides a series of tips for app developers, like ensuring no links are ever broken, that there’s no place-holder content and a bunch more, too. Go take a read. [Common App Rejections via Cult of Mac]

False Visualizations: Sizing Circles in Infographics

Infographic cautions here from Randy Krum:

False Visualizations: Sizing Circles in Infographics

“Accuracy is the most important aspect of an infographic design!

Last week, the article The Truth about the Ice Bucket Challenge by Julia Belluz on Vox Media included the infographic,Where We Donate vs. Diseases That Kill Us, that used proportionally sized circles as its data visualization. The problem with this design is that the circle sizes don’t match the values shown. This is a false visualization and significantly over exaggerates the smaller amounts of money contributed to each charity and the deaths attributed to each cause.

This causes problems because readers often just look at the visuals without reading the actual numbers. They start with the assumption that a visualization accurately represents the data. The Vox Media story and infographic already have over 12,000 shares on Facebook, and this is a great case study for designers to understand how important it is to visualize data accurately.

As readers, we see the area of two-dimensional shapes on the page to represent the different values, but design software only allows width and height adjustments to size shapes. Designers make the mistake of adjusting the diameter of circles to match the data instead of the area, which incorrectly sizes the circles dramatically. It takes some geometry calculations in a spreadsheet to find the areas and then calculate the appropriate diameters for each circle. To demonstrate, I created this corrected version of the infographic.

False Visualizations: Sizing Circles in Infographics Revised

My Google Docs spreadsheet of the correct circle area and diameter calculations is available here.

Assuming this was a design mistake, and there was no intent to deceive the audience, this is a common mistake that many designers make.  So many designers, that I included an entire section on this topic in the Cool Infographics bookto help designers understand how to size the area of circles.

I made one other improvement to the corrected design above by removing the color legend and listing the charities and causes of death right next to the appropriate circles. This makes the whole visualization easier for the audience to read by eliminating the need to look back-and-forth from the circles to the color legend to figure out what each circle represents.  Placing the text next to each circle keeps the information in the reader’s field of view which minimizes eye movement.

Sticking with the circles data visualization style, I wanted to take the design a little bit further. I would recommend one of two alternate improvements.  First, adding colored connecting lines is one way to make it easier for the audience to find the related circles in the columns sorted in descending order.

A second alternative would be to sort the lists to line up the related circles.  This makes it much easier for the audience to see the direct comparisons between charitable contributions and death rates related to the same cause.

I’m passing over any discussion about whether using proportionally sized circles (a bubble chart) is the best visualization method for this data. If a designer makes the choice to use sized shapes, my point is that the data visualizations in the infographic must match the numbers using area.  David Mendoza published a good analysis worth reading and designed an alternative way to visualize the data in his article, This Bubble Chart Is Killing Me.

How else would you improve this design?

NOTE: I was able to contact the designer who created the infographic at Vox Media, and he had already realized his error after the infographic had been published. As I had guessed, he had mistakenly adjusted the diameter of the circles instead of the area. He told me that he’s working on updating the official infographic design in the article, but it hasn’t been published on the Vox Media site yet.


Update on Friday, August 29, 2014 at 3:40PM by Randy

As the designer from Vox promised, they have now posted a corrected version of the Where We Donate vs. Diseases That Kill Us infographic with the circles sized correctly.  Kudos to Vox for handling the error professionally and correcting it quickly.”

Critical information literacy in practice: an interpretive synthesis

“The purpose of this study was to review and synthesize the literature of critical information literacy through a critical interpretive practitioner lens in order to uncover pedagogy and instructional content to inform my own teaching practice and that of other individual teaching librarians who wish to take a critical approach to information literacy with undergraduate students.”
