RE: 15m downloads? Here is a chart of Poynt installations over the last 30 days originating from the Andriod Market, it shows a general up trend.
LAST 30 DAYS
This doesn't include preloads or the many other places to get Poynt for Andriod, and it certainly doesn't incude the other platforms. I don't know how acurate it is the other day it was showing a surprising decline but I think it was just a hole n the data as it corrected hugely. Any how its a third party visual representation indicating how things are ramping to the positive on the user adds.
