OT: Could someone from outside South Africa try to install iSinkwe?

[Linux for blind general discussion]

Good day,
We at the Voice Computing research group at the CSIR have released an 
Android app called isinkwe.
It is an epub3 reader supporting media overlays.

I would like to verify that it is installable from another country than 
South Africa.
It is a free install.
Just search for isinkwe in the playstore.
It works, but is still beta software.
It will likely be discussed at a conference in the Netherlands if the 
paper is accepted.
People can answer me off-list if they like.
TIA, Willem
