Verdict
The clearest difference is price: 2357P at Free against Sync's $0.99. 2357P also leads on update cadence (every 15 months vs every 40 months). Sync's advantage is rating (4.8 vs 3.0) and ratings volume (33 vs 2). On ads, in-app purchases, monetization model and device support there is nothing between them.
