# Baseline vs Peptide Tracker

The clearest difference is ratings volume: Peptide Tracker at 53 against Baseline's 1. On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Baseline sells 2 in-app purchases, starting at $4.99 per month and Peptide Tracker sells 2 in-app purchases, starting at $9.99 per month. 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 Baseline against 5.0 for Peptide Tracker. That said, the two scores are not equally well evidenced: Peptide Tracker has 53 ratings behind it against 1, so its average is the more settled of the two.

Baseline ships an update weekly, Peptide Tracker every 5 days. The most recent releases landed on October 10, 2026 and October 22, 2026 respectively.
