Verdict
The clearest difference is in-app purchases: ESST at none against Peptide Tracker's 7. ESST also leads on rating (4.9 vs 4.7) and iOS requirement (14.0 vs 18.6). Peptide Tracker's advantage is update cadence (weekly vs every 3 months) and ratings volume (305 vs 10). On price, ads and device support there is nothing between them.
