# Smart Peptide Tracker vs PepLog

The clearest difference is in-app purchases: PepLog at none against Smart Peptide Tracker's 9. PepLog also leads on review sentiment (100% vs 86%). Smart Peptide Tracker's advantage is rating (4.7 vs 4.4) and update cadence (every 5 days vs every 2 weeks). On price, ads and device support there is nothing between them.

Both are free to download. Smart Peptide Tracker sells 9 one-off in-app purchases. PepLog asks for nothing beyond the download.

Smart Peptide Tracker holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Smart Peptide Tracker has 162 ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 86% of Smart Peptide Tracker'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.

Smart Peptide Tracker ships an update every 5 days, PepLog every 2 weeks. The most recent releases landed on October 17, 2026 and October 8, 2026 respectively.
