# Cosmo vs MasterJi

The clearest difference is in-app purchases: MasterJi at none against Cosmo's 4. MasterJi also leads on update cadence (weekly vs fortnightly) and device support (3 vs 1). Cosmo's advantage is ratings volume (856 vs 1). On price, rating, ads and iOS requirement there is nothing between them.

Both are free to download. Cosmo sells 4 in-app purchases, starting at $12.99 per month. MasterJi asks for nothing beyond the download.

MasterJi holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cosmo has 856 ratings behind it against 1, so its average is the more settled of the two.
