App Quality Alliance (AQuA) found that 61 per cent of developers have had an app rejected by Apple’s App Store and 67 per cent face challenges in understanding the App Store testing requirements prior to submission.

The non-profit organisation that supports quality app development has responded to its survey findings by launching a set of testing criteria for iOS developers.

The free testing criteria include guidance on user interface, performance, functionality, security, privacy, media, data handling and stability.

AQuA has previously focused on Android and Java, but is now accepting iOS apps into its Quality App Directory, a resource for companies looking to buy the best quality apps and collaborate with the best developers.

“While many in the industry agree that there are more quality apps in the App Store than elsewhere, developers are seeking measurable and actionable guidance to help ensure a faster and more successful iOS submission process and our testing criteria delivers that,” said AQuA executive director Martin Wrigley.
