# PeptideJournal vs Peptide Tracker

The clearest difference is price: Peptide Tracker at Free against PeptideJournal's $5.99. Peptide Tracker also leads on rating (4.7 vs 4.3) and ratings volume (306 vs 20). PeptideJournal's advantage is in-app purchases (none vs 7) and chart position (#187 vs unranked). On update cadence, ads, device support and iOS requirement there is nothing between them.

Peptide Tracker is free to download; PeptideJournal costs $5.99 up front. Peptide Tracker sells 7 in-app purchases, starting at $3.99 per 7 days. PeptideJournal asks for nothing beyond the download.

Peptide Tracker holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Peptide Tracker has 306 ratings behind it against 20, so its average is the more settled of the two. Written reviews point the same way: 63% of PeptideJournal's written reviews are positive against 77% of Peptide Tracker's.
