# Slym vs CalKit

The clearest difference is in-app purchases: Slym at none against CalKit's 3. Slym also leads on ratings volume (150 vs 14) and iOS requirement (13.2 vs 26.6). CalKit's advantage is review sentiment (60% vs 38%). On price, rating, ads and monetization model there is nothing between them.

Both are free to download. CalKit sells 3 in-app purchases, starting at $4.99 per 7 days. Slym asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.2 for Slym against 4.2 for CalKit. That said, the two scores are not equally well evidenced: Slym has 150 ratings behind it against 14, so its average is the more settled of the two. Written reviews are what separate them: 38% of Slym's written reviews are positive against 60% of CalKit's.
