Indie developer David Smith recently published some interesting statistics to his personal blog regarding the adoption rate of iOS versions 5.0 and later. Apple released iOS 5 last October, and has since seeded two incremental updates.

Smith pulled the data from the user base of his popular iOS app, Audiobooks. The app sees about 100 thousand downloads on a weekly basis, so admittedly, its users provide a nice little test market. Now, on to the numbers…

According to Smith’s report, 61% of users are currently running on the latest version of iOS — iOS 5.1. That’s a pretty big number considering the software was released just under three weeks ago at Apple’s iPad event.

Going down the line, the numbers show that 18% of iOS users are running version 5.0.1. This isn’t too surprising given the fact that a) there isn’t an untethered jailbreak available for iOS 5.1 yet, and b) 5.1 is still fairly new.

Last but not least, Smith’s data shows that 1% of users are running iOS 5.0. But perhaps even more interesting is that it also shows that nearly 20% are still using a version of iOS 4.X. What’s the deal with that?

Even though this data obviously doesn’t represent the majority of iOS users, it does provide some nice insight into the world of iOS version adoption. These results bode well for developers, who typically like to see as little fragmentation as possible.

In comparison, less than 2% of Android users are running the latest version of the mobile OS (Ice Cream Sandwich). While this, as Smith points out, likely has more to do with availability than anything else, it still helps explain developers’ frustration with the platform.

What version of iOS are you running?

[The Loop]

  • TBH… I never heard of “audiobooks” until i read this news .. so thats one less figure.
    and yes the results he finds are fairly interesting. But his app of 100,000 downloads probably only covers about 20% of the iDevice population.

    Waiting for untether (5.0.1 on iPhone4s)
    5.1 (iPad 3 gen)

  • Kok Hean

    39% are jailbroken untethered.

  • i’m running 5.1 on all my devices. iphone4 is jailbroken. tether vs untether isn’t really a big deal to me since i never reboot my phone nor do i ever let the battery completely discharge.

    • can you respring? i can’t remember i haven’t had a tethered jailbreak in a few years

      • You can respring on a tethered jailbreak.

      • then at least you can play around with tweaks. thanks justin~

  • I’m jailbroken on 5.0.1 with my iPhone 4S and my “New iPad” (iPad 3) is obviously running 5.1.

  • Me? On 5.0.1 waiting for a exploit on 5.1…..

    Patience is a virtue guys…..

      My guess is the people still on 4.x are those with old 3G phones since the latest you can go is 4.2.1 and still be software unlockable. Or old 4.3.3 untethers and iPad1

  • xmenlegends360

    Im on 4.3.3. Using jailbreAme allowed me to have a little bit more ram available to use.

  • 3.1.3!
