# Slopes vs CPAce

The clearest difference is in-app purchases: Slopes at none against CPAce's 2. Slopes also leads on ratings volume (41 vs 6). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. CPAce sells 2 in-app purchases, starting at $9.99 per month. Slopes asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Slopes against 5.0 for CPAce. That said, the two scores are not equally well evidenced: Slopes has 41 ratings behind it against 6, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
