After launching an HD version of SLAP! for $1.99 we received only a small handful of downloads. We decided to go free for the Mother’s day weekend even though we had no IAP. To our surprise the game received downloads in excess of 10k per day with no revenue. The majority of these downloads came from China so SLAP! HD enjoyed a #1 spot (ipad, Overall, Free) for a few days. After switching the app back to paid, downloads rates reduced back down to a trickle.
Next step – get an in-app-purchase into SLAP! HD and switch back to free. Hopefully it has the same success the second time around and hopefully the IAP converts.
