# Peptide Tracker vs Ampulix

The clearest difference is ratings volume: Peptide Tracker at 442 against Ampulix's 3. Ampulix's advantage is review sentiment (100% vs 77%) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Peptide Tracker sells 7 in-app purchases, starting at $0.99 per 7 days and Ampulix sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Ampulix holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Peptide Tracker has 442 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 77% of Peptide Tracker's written reviews are positive against 100% of Ampulix's.

Peptide Tracker ships an update fortnightly, Ampulix every 5 days. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
