# Harmonyland vs Sine

The clearest difference is update cadence: Sine at daily against Harmonyland's every 5 weeks. Sine also leads on ratings volume (393 vs 1) and chart position (#85 vs unranked). Harmonyland's advantage is monetization model (free vs freemium). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Harmonyland sells 1 in-app purchase, starting at $39.99 per year and Sine sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Harmonyland against 4.9 for Sine. That said, the two scores are not equally well evidenced: Sine has 393 ratings behind it against 1, so its average is the more settled of the two.
