Verdict
The clearest difference is ratings volume: Smart Peptide Tracker at 167 against Bio Log's 2. Smart Peptide Tracker also leads on update cadence (every 5 days vs every 3 weeks) and device support (3 vs 1). Bio Log's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.
