I’ve been collecting data for both Scribattle purchases and Scribattle Lite downloads, and have some results to share. Like most other reports of this nature that I’ve seen, I’m going to be coy and not show any precise numbers, but rather some graphs that show the relative growth for these products. These charts begin on February 10 (the day Scribattle first appeared on the App Store) and March 1. Blue dots are Scribattle, green dots are Scribattle Lite. Scribattle Lite was only available during the last five days of this period.

The first chart shows a nice rising slope for Scribattle Lite, and what seems to be a complete flatline for Scribattle. This is due to the fact that the free downloads completely dwarf the paid downloads, so that none of the changes in paid downloads equate to even a single pixel on this scale.

The second chart reveals the true growth in Scribattle sales by scaling them up to match the Scribattle Lite downloads. Basically, if you plotted Scribattle sales by themselves, and then overlaid that on top of a plot of Scribattle Lite downloads by themselves, this is what you would see.

Finally, for the sake of showing both sets of numbers relative to each other, while still allowing some viewing of the smaller values in the Scribattle sales, here are is a logarithmic view of the same data shown in the first chart. The nice straight rising lines toward the end, especially for Scribattle Lite, show periods of exponential growth. What you’re seeing is basically a doubling of the number of Scribattle Lite downloads each of the last 4 days, and nearly the same kind of increase for Scribattle sales!

I’ve only had my Lite version on the App Store for 5 days, but even at this early stage I feel safe in saying that in my case, releasing a Lite version has been a huge win for sales of the full version. Not an epic win (yet), but still a huge win.
