Verdict

The call

The clearest difference is price: PepTracker at Free against PeptideJournal's $5.99. PepTracker also leads on rating (4.7 vs 4.3) and ratings volume (469 vs 20). PeptideJournal's advantage is in-app purchases (none vs 8) and update cadence (weekly vs every 3 weeks). On ads, device support and iOS requirement there is nothing between them.
