After release, they'll be adding information to Geo Walk in various updates, and Toporkov says the company will listen very closely to the community, adding in suggested information about local landmarks or history when possible. They'd also like to eventually add sounds and videos to the map, rather than just browsing around text points on the globe as you can now. Toporkov says that with Geo Walk, the company is hoping to show customers that they're not just an astronomy company -- while both of their apps so far have focused on space, what they really want to do is just make entertaining educational apps, whatever the subject.
I asked the developers about iPhone 4, and they said that they'd be working as hard as possible to make sure all of their current apps were updated for the new handset, as well as staying backwards-compatible with previous versions of iOS and previous iPhones. When iPhone 4 comes out, they will have three different versions of the apps running, and the app will check to see which one to run when it starts up. They're excited to play around with the new gyroscope, too -- "for Star Walk," they said, "that will be very important."
For all of their success, Toporkov says he's delighted with Apple and the App Store. The company has released other mobile apps, and examined other marketplaces and platforms, but they're sticking with Apple's platform both because Apple's plan allows them to sell apps more easily and gain more profit from those sales, and because they have a larger market, both in the US and Russia as well as Japan and Europe. "Some developers will blame Apple for being closed, or having an unpredictable approval process," Toporkov told me. "For us, that's all true, too. But still, we can say thanks for Apple."
