With regards to a free version. That is in the plans. It's a fair amount of work to create and maintain two versions, so the decision was to put the paid version out first. In addition to keeping it simple, we need to start generating revenue for future development. The board only approved the investment for the first version of the app, not for unlimited ongoing development. If we aren't successful in selling the app so it can generate enough revenue to continue development, we may not pursue implementing the long list of possible features.
Assuming sales are reasonable, we will continue development, and then release a free and a paid version. Anyone that buys the initial paid version will be able to upgrade to all the new features in the paid version without any additional cost (we can't guarantee this, but most likely for at least a year or two). The free version will have basic features, and ads, and will be encouraging people to upgrade.
As far as the Android version goes, development has been approved, and will start soon. I use a Motorola Droid X as my main phone. Dave Gentry and Dave Nesbitt, and other key individuals on the extended development team, have Android devices, so we are all very much looking forward to the Android version!
We are anxiously awaiting the Apple approval. It has been in the "Waiting for Review" status since last Friday, and the average time for review is around 7 or 8 business days (Mon-Fri). There's no guarantee that we'll pass the first review, though. This is our first attempt.
