Verdict

The call

The clearest difference is review sentiment: Peptide Diet at 100% against Stackr's 67%. Peptide Diet also leads on rating (4.8 vs 4.4) and device support (3 vs 1). Stackr's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (189 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
