# Sleepcraft vs Mutterly

The clearest difference is monetization model: Sleepcraft at free against Mutterly's freemium. Sleepcraft also leads on ratings volume (28 vs 1). Mutterly's advantage is update cadence (every 3 days vs weekly). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Sleepcraft sells 4 in-app purchases, starting at $9.99 per month and Mutterly sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
