Slopes is an interactive environment for exploring graphical solutions to ordinary differential equations. Slopes consists of six activities with preloaded examples to get you started and the ability to input your own content. "Slopefields" and “Phase Planes” both plot vector fields and solutions corresponding to multiple initial conditions. “Systems” dynamically solves systems of up to six equations. “Oscillations” solves second-order constant coefficient equations and animates the corresponding spring-mass system or RLC circuit. “Methods” constructs numerical approximations of a single ordinary differential equation using Euler’s method as well as Second and Fourth Order Runge-Kutta methods. "Bifurcations" creates a bifurcation diagram and shows the stability of equilibrium points. Slopes is a playground for ODEs. You can use it for homework, in-class activities or a new research project.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
