# Stackr vs Peptide Diet

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.

Both are free to download. Stackr sells 7 in-app purchases, starting at $7.99 per 7 days and Peptide Diet sells 10 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.

Peptide Diet holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Stackr has 189 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 67% of Stackr's written reviews are positive against 100% of Peptide Diet's.

Stackr ships an update every 4 days, Peptide Diet every 3 weeks. Both last shipped on October 24, 2026.
