Flurry Analytics
We’ve added anonymous Flurry Analytics to both 3D Camera and 3D Camera Lite as of version 1.3. Our hope is that the data will give us insight into app usage patterns and help us prioritize upcoming features and fixes.
While we’ve only been collecting analytics for about a month, this data represents 23,190 unique users across 72,899 sessions. There is a lot more information than we could easily share in a blog post, so we’ve selected a few items that may help others decide which devices and/or firmware versions to target for their own apps.
The first chart shows the device breakdown. Note that 3D Camera and 3D Camera Lite only work with the iPhone, so no iPods are listed. We were (happily) surprised to see such a high percentage of 3GS devices.

The second chart reports firmware versions. As of version 1.3, 3D Camera and 3D Camera Lite both require firmware 3.0 or later, so no older versions are included in this report. For the curious, we haven’t received a single e-mail or complaint since we decided to require 3.0.

We also capture the amount of free memory available when the apps start. On average, there is 19,148,063 bytes available. This is important to us, because 3D Camera blends two bitmap images into a third, and the app is often skating on the edge of available memory.
For 3D Camera specifically, here are some other interesting statistics:
- The average length of a session is 3.3 minutes (a session includes app start through app termination).
- Photos are taken with the camera three times more often than they’re selected from the album.
- Most users save their 3D image to the photo album, followed by e-mail, Facebook, then Twitter.
- The most common 3D format to save to the album is a grey anaglyph. The next most common format is a parallel stereogram, and it’s saved half as many times.
- For users that send images to Twitter, the wigglegram format is the most popular (by far).
- Surprisingly, no errors or exceptions have been reported. While we pride ourselves on quality code, in our minds, this data point is suspect.
Hopefully, this data will help others understand the current breakdown of devices, firmware versions, and available memory so that they can make more informed decisions.
