Verdict
The clearest difference is in-app purchases: BoxZombie at none against In Sync's 1. BoxZombie also leads on iOS requirement (10.0 vs 12.0). In Sync's advantage is ads (none vs shown) and update cadence (every 5 weeks vs every 6 months). On price and device support there is nothing between them.
