ACT/The App Association has released a new study titled "iOS App Economy Report," which includes some interesting insights about the mobile development industry. One of the most notable is the fact that nearly a third (32 percent) of the developers currently on the lists of top apps in the App Store weren't ranked a year ago. Other noteworthy findings include the following:
- 77 percent of top mobile development firms are not located in Silicon Valley.
- 80 percent of top iOS apps are made by U.S. companies.
- 40 percent of top Apple Watch apps are in the "health" category.
