I get a lot of good feedback from developers who say these posts are helpful, so I don’t feel bad spamming everyone with updates every few months.
Here’s my most recent data from people using the Instapaper app:
Compared to August’s data, you can see a few unsurprising trends:
- iOS 5 adoption is gradually rising, but it’s too early to require it. (It’s only 49 days old.)
- iOS 4+ adoption, now at 98.8%, is so ubiquitous that it’s very safe to require it.1
Developers of CPU-intensive iPhone apps and games can celebrate the continued infiltration of faster hardware, with at-least-3GS-class CPUs in 94.39% of iPhones and iPod Touches. Apps that need high performance can probably start requiring iOS 4.3 (87.8%) to forcefully cut support for the much slower old CPU in the iPhone 1, iPhone 3G, and 1-2G iPod Touches.
With iPads included, 3GS-or-better CPUs are in 97.4%, A4-or-better CPUs are in 89.4%, and A5 CPUs are in 36.4% of devices in this sample.
We can also extract a bit of insight into Apple’s device sales:
- The iPhone 4S has sold well so far, especially given that it’s only been out for 47 days.
- iPad 2 sales have been steady, but seemingly not mind-blowing. We’ll see what happens after the holidays: last year, I saw a huge rise in iPad sales on Christmas and the following few days.
- Still, very few iPad 2 buyers choose the Verizon 3G model. (I did, but I wish I got the GSM version.)
Instapaper started requiring iOS 4.2 recently. I’ve heard from only one person who was upset that it stopped working on his original iPhone, but he also mentioned that lots of his other apps were recently updated to require iOS 4 as well. ↩︎
