# Peptide Tracker vs Vial

The clearest difference is review sentiment: Vial at 100% against Peptide Tracker's 50%. Vial also leads on monetization model (freemium vs subscription). Peptide Tracker's advantage is rating (4.7 vs 3.4) and ratings volume (177 vs 5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Peptide Tracker sells 10 in-app purchases, starting at $7.99 per 7 days and Vial sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Peptide Tracker holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Peptide Tracker has 177 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 50% of Peptide Tracker's written reviews are positive against 100% of Vial's, so the app with the better star average is not the one people write more warmly about.

Peptide Tracker ships an update weekly, Vial every 11 days. The most recent releases landed on November 9, 2026 and November 5, 2026 respectively.
