# MyCircadianApp vs Moldmap

The clearest difference is ratings volume: MyCircadianApp at 265 against Moldmap's 4. Moldmap's advantage is update cadence (weekly vs every 4 weeks). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. MyCircadianApp sells 7 in-app purchases, starting at $3.99 per month and Moldmap sells 8 in-app purchases, starting at $11.99 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 — 4.9 for MyCircadianApp against 5.0 for Moldmap. That said, the two scores are not equally well evidenced: MyCircadianApp has 265 ratings behind it against 4, so its average is the more settled of the two.
