# Protocol Zero vs GymPact

The clearest difference is monetization model: GymPact at freemium against Protocol Zero's subscription. GymPact also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 17.2). Protocol Zero's advantage is ratings volume (201 vs 2). On price and in-app purchases there is nothing between them.

Both are free to download. Protocol Zero sells 5 in-app purchases, starting at $12.99 per month and GymPact sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

GymPact holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Protocol Zero has 201 ratings behind it against 2, so its average is the more settled of the two.
