Verdict

The call

The clearest difference is price: World Sync at Free against SwissSystem's $7.99. World Sync also leads on rating (5.0 vs 4.7) and update cadence (fortnightly vs every 6 weeks). SwissSystem's advantage is ratings volume (12 vs 1) and device support (3 vs 1). On ads and in-app purchases there is nothing between them.
