As tweeted by PCalc developer James Thomson today, he will be forced to remove the app’s iOS 8 widget. Following an approval that saw PCalc 3.3 launch alongside iOS 8 and a feature in Apple’s “Great Apps for iOS 8” App Store section, the company has informed Thomson that “Notification Center widgets on iOS cannot perform any calculations”.

Curious app rejections aren’t new to the App Store, but being forced to remove a feature that was approved, featured by the App Store team, and appreciated by thousands of users is a different story. As Thomson tweeted, he invested time and resources into the development of the widget, which was a fantastic addition to the app and a nice way to perform quick calculations directly in the Today view of Notification Center. More importantly, it was a great showcase of the new capabilities of iOS 8.

Thomson wasn’t alone in thinking that a widget calculator would be a good idea: dozens of iOS 8 widgets with the same feature have been released since last month (such as Wdgts) and Apple itself offers a calculator widget in OS X Yosemite.

But even with the following examples in mind, being forced to remove apps or features that had been previously approved isn’t news either (case in point). Rather, what is disappointing is the persistence of contradicting signals from a company that many developers saw as “more open” after WWDC ‘14. Developers like Thomson will keep finding themselves in the position of risking to implement a feature or create an app that may be approved, gain users, and be shut down by Apple for a sudden policy change.

PCalc will continue to be a great app even without its widget. But at some point, we’ll have to wonder whether technology limitations or murky App Store policies are truly holding iOS back, preventing developers from building innovative iOS-first apps that dare to go beyond the status quo. Today, that’s happening to a calculator widget.
