Verdict
The clearest difference is in-app purchases: Sálmabók at none against Reverse Singing's 2. Sálmabók also leads on iOS requirement (15.1 vs 17.0). Reverse Singing's advantage is update cadence (every 3 weeks vs every 71 months). On price, ads and device support there is nothing between them.
