I'm also planning and building on a flashcard app; and am facing a similar dilemma on whether to monetize (make it SaaS) or go all out open-source. At the moment my barometer seems to be leaning towards open source. I already have REST API backend done, and am working on UI.

------

The only novelty on my app is that it uses an algorithm based on upvotes/downvotes (e.g. HN, Reddit, etc) to measure card performance rather than a variant based on SuperMemo and friends.

I already wrote a spec on it (feel free to steal =P): https://github.com/grokdb/spec
