# Peptide Tracker & Calculator vs PepLog

The clearest difference is review sentiment: PepLog at 100% against Peptide Tracker & Calculator's 70%. PepLog also leads on monetization model (free vs free with in-app purchases). Peptide Tracker & Calculator's advantage is rating (4.8 vs 4.4) and update cadence (every 2 days vs fortnightly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Peptide Tracker & Calculator sells 4 in-app purchases, starting at $3.99 per month and PepLog sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Peptide Tracker & Calculator holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Peptide Tracker & Calculator has 590 ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 70% of Peptide Tracker & Calculator's written reviews are positive against 100% of PepLog's, so the app with the better star average is not the one people write more warmly about.

Peptide Tracker & Calculator ships an update every 2 days, PepLog fortnightly. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
