Ive downloaded and looked at a few of the apps. Very few are in English. The ones Ive found that are were Danamas and Modalku. You can dig around a little bit, but at some point you have to register to go any farther. I wanted to see what one of the actual lending pages looks like, so in Modalku you can go to the sign up as a lender page, but it will ask you which of these 3 countries are you from "Indonesia, Malaysia, or Singapore".
KFUND could probably throw the app out to everyone, but maybe it saves on people trying to sign up from out of country.
