- Marketing: the Android market is such a big place I'm sure it's easy for apps to get lost. Android users: where do you go to hear about cool new apps?
- Free version: I've heard that Android users are much less likely to pay for apps than those on other platforms. Maybe I should make a free version that has ads. I'm not a huge fan of in-app ads, though, and I can't imagine they'd make that much money. Plus, that's potentially a bunch more users to support. And other flight-tracking apps aren't free...
- Amazon Market: I'm also deciding whether or not to submit to the Amazon App Store. The terms are not favorable to developers, as Amazon can set your app to be any price they want. (hopefully not less than 99 cents?) But it's the only way to get on the Kindle Fire, and while I didn't optimize FlightPredictor for that big a screen, a beta tester used it on a 7" tablet and said it worked fine.
Maybe part of the problem is neither Google nor Amazon care that much about app sales?
Anyway, I'm more than open to suggestions.
