# PepTracker vs Protocol

The clearest difference is update cadence: Protocol at every 2 days against PepTracker's every 2 weeks. Protocol also leads on review sentiment (100% vs 77%) and rating (5.0 vs 4.7). PepTracker's advantage is ratings volume (413 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PepTracker sells 2 in-app purchases, starting at $4.99 per month and Protocol sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Protocol holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PepTracker has 413 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 77% of PepTracker's written reviews are positive against 100% of Protocol's.

PepTracker ships an update every 2 weeks, Protocol every 2 days. The most recent releases landed on October 11, 2026 and September 29, 2026 respectively.
