# One Second vs Snap Second

The clearest difference is review sentiment: Snap Second at 86% against One Second's 31%. Snap Second also leads on ads (none vs shown) and rating (4.8 vs 4.5). One Second's advantage is ratings volume (3.6K vs 16) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.
