Verdict

The call

The clearest difference is rating: Rosetta Stone Sapphire at 4.6 against ReabDook's 3.0. Rosetta Stone Sapphire also leads on ads (none vs shown) and review sentiment (29% vs 0%). ReabDook's advantage is update cadence (every 6 days vs every 2 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
