business model:
1. release gpl source: as soon as it's reasonably useful to me, and there aren't any super-easy-to-add features from the basic set left to add
2. mearnag site for power users - apk download - paypal donation or maybe kickstarter
3. expensive hand-holding service (data hosting, data-capture setup consulting, sanity checking, phone support, 1 analysis included)
4. free market app with IAP donation and hand-holding purchase
5. automated cheaper hosted option (separate app (assumed settings hidden) and IAP)
