Verdict
The clearest difference is update cadence: StackTrax at daily against Smart Peptide Tracker's every 5 days. StackTrax also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 87%). Smart Peptide Tracker's advantage is ratings volume (167 vs 8). On price, ads, in-app purchases and monetization model there is nothing between them.
