Verdict

The call

The clearest difference is in-app purchases: Sincey at none against MyBox's 1. Sincey also leads on rating (5.0 vs 4.7) and update cadence (every 4 days vs every 9 days). MyBox's advantage is ratings volume (6 vs 1) and iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
