Great advice, thanks for the insight. Would love to look at Freemium but flat out working on other improvements and functionality at the moment to include it, but here's an idea - do you think (in your opinion, and anyone else who is reading) that doing a short-term promotion here and reducing the app to $0.99 (the lowest price I can make it, because it's not possible to swap between paid and free in Android Market) would be enough to entice people who read about the app here to try it and provide reviews to help get the word out?

I'll certainly spend time working on the wording in the Market listing to see if we can get moved up closer to the top, or at least start appearing on the first page and I'll also check out that link. Thanks again for your feedback, I really do appreciate it.

Can you make a free version with reduced functionality, called, say, Gold Tasks? Cross promote from there or do in-app purchases/upgrades if Android has that.

Yeah that's sounding like a pretty good idea so people can get a feel for the app and then hopefully upgrade to get some of the more advanced functionality. Thanks for the feedback.
