Verdict
The clearest difference is review sentiment: SyncJet at 100% against Flapper's 75%. SyncJet also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.7). Flapper's advantage is ratings volume (144 vs 3) and update cadence (fortnightly vs every 6 weeks). On price, ads, in-app purchases and device support there is nothing between them.
