Thanks for getting back to me.
Our company is in fact an autonomous unit within a large, international university. Since our backers have poured so many resources into developing the app, the only way we're going to be able to get their investment back is by marketing the app to the biggest, richest educational market on the planet. We're a non-profit, but we certainly can't keep developing the app without a consistent revenue stream.
The app is very much accessible to children all over the world. In fact, that's one of our selling points: its content is truly global, covering everything from Ancient Greece to Angkor, chemistry to crocodiles. And since it's also fully narrated, it has plenty of potential as an ESL tool.
At this stage, however, we can't simply give the app away. It's taken a lot of time and money to put this thing together.
If you don't mind, I would like to know more about your opinion of the Vietnamese market and your access to schools and educators there. Please PM me at a time of your convenience and we can discuss this at greater length.
