Oomph is a content distributor like Google Play. The main difference is that it is tailor-made just for the Indonesian Android market, mainly due to payment methods that it accepts. It lets customers pay for downloads via prepaid mobile credit which is referred to as “pulsa” in Indonesia. To date Google Play does not support carrier billing in Indonesia.
Oomph currently has more than 4.5 million registered users. Forecast to reach 10 million users by the end of next year. Oomph monetizes on a pay-per-download basis.
