# D Minder Pro vs MyCircadianApp

The clearest difference is review sentiment: MyCircadianApp at 99% against D Minder Pro's 34%. MyCircadianApp also leads on rating (4.9 vs 4.0) and ads (none vs shown). D Minder Pro's advantage is update cadence (every 2 days vs every 4 weeks) and ratings volume (1.8K vs 266). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. D Minder Pro sells 2 one-off in-app purchases and MyCircadianApp sells 7 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

MyCircadianApp holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: D Minder Pro has 1.8K ratings behind it against 266, so its average is the more settled of the two.
