# Viking Synth vs Harmonus

The clearest difference is review sentiment: Harmonus at 100% against Viking Synth's 71%. Harmonus also leads on price ($2.99 vs $3.99). Viking Synth's advantage is rating (4.7 vs 4.4). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
