UPDATE: As of about 4:30pm ET, the App Store seems to be working again and Apple's Service page reports that it's running. Back to promoting those apps, everyone -- with an eye on the stability of the app store, just to be safe. Original post below.

Last night, Apple withdrew iOS 8.0.1 after it surfaced that the update was causing problems with cellular connectivity for iPhone 6 users. That's a pretty serious bug -- but it turns out that according to our data, only a very small percentage of users with the new phones had actually upgraded -- and many of them have used Apple's instructions on how to revert to the original iOS 8.0.

Our iOS 8 Activity Tracker is showing real-time iOS 8 events from around the world, illustrating the rapid switch to the new operating system. (Fairly rapid, anyway: not nearly as fast as iOS 7 last year, but still impressive.) The most dramatic images came from the first 24 hours, though, as early adopters rushed to get the new software.

September and October are exciting - and scary - months for app marketers. It’s the season for new Apple devices, and with them a new version of iOS.  When users update their operating system or move to new phones, they often re-evaluate their app choices and clean house on their phones. "What do I delete and what do I keep? Should I look at new apps to install?"

That’s the scary part for app marketers: it’s an easy time to lose a connection with a customer who might not reinstall every app on their phone.    

After weeks of breathless conjecture -- will they introduce a new iPhone? (no!) or home automation? (yes!) -- Apple used yesterday's WWDC keynote to unveil a slew of changes and updates to OS X, iOS, and the App Store, but no new hardware. Instead, the focus of the event was squarely on developers. Yes, new features like improvements to iMessage, family sharing, and OS X to iOS AirDrop are nice updates for consumers.

In the day-to-day excitement and chaos of running a fast-growing technology business, it's sometimes hard to get perspective on where we really fit in the larger community. Because of that, outside perspectives like today's Boston Magazine article on the state of ad tech in Boston are incredibly valuable. 

Most US Apple app developers understand that for every $0.99 purchase on iTunes, they make $0.70, a 70% cut. However, for international sales, that percentage varies due to a few factors

In rapidly evolving industries, uncertainty can be a killer -- so the introduction of the Advertising Identifier (IDFA) with iOS 6 was a welcome relief. The app marketing industry needed a privacy-respecting, industry-standard way to attribute ad performance, and the IDFA seemed like an ideal answer to an unsettled situation. 

Earlier this week Apple released its updated figures on iOS adoption, showing that 87 percent of devices are running on iOS 7, 11 percent on iOS 6 and 2 percent on earlier OS’.

And would you look at that - an identical representation of what Fiksu is seeing on its iOS adoption tracker!

Sometimes it takes a bit of data to understand the impact of something you already intuitively knew. The growth of mobile is widely reported, but user habits are increasingly shifting many activities away from the traditional web and onto mobile. In fact, mobile-only users -- those who only use phones or tablets for common online activities -- are increasingly becoming a force in the market.
