Verdict
The clearest difference is price: Spark at Free against The Sight Reader's $2.99. Spark also leads on update cadence (every 2 weeks vs every 10 months) and ratings volume (25K vs 1). The Sight Reader's advantage is in-app purchases (none vs 1). On rating, ads, device support and iOS requirement there is nothing between them.
