# Teach Note vs 懂音律

The clearest difference is update cadence: 懂音律 at every 10 days against Teach Note's every 5 weeks. 懂音律 also leads on rating (4.9 vs 4.7) and iOS requirement (14.0 vs 18.6). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Teach Note sells 10 in-app purchases, starting at $2.99 per month and 懂音律 sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
