# Smart Runner vs Peptaflow

The clearest difference is monetization model: Peptaflow at free against Smart Runner's free with in-app purchases. Smart Runner's advantage is ratings volume (7 vs 1) and device support (3 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Smart Runner sells 3 in-app purchases, starting at $14.99 per year and Peptaflow sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Smart Runner against 5.0 for Peptaflow. That said, the two scores are not equally well evidenced: Smart Runner has 7 ratings behind it against 1, so its average is the more settled of the two.
