# Peptide Tracker vs PeptidesAI

The clearest difference is ads: PeptidesAI at none against Peptide Tracker's shown. PeptidesAI also leads on rating (5.0 vs 4.8). Peptide Tracker's advantage is ratings volume (114 vs 3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Peptide Tracker sells 12 in-app purchases, starting at $7.99 per 7 days and PeptidesAI sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PeptidesAI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Peptide Tracker has 114 ratings behind it against 3, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 19, 2026 and October 7, 2026 respectively.
