# Peptide Vault vs Stackr

The clearest difference is monetization model: Stackr at freemium against Peptide Vault's subscription. Stackr also leads on ratings volume (126 vs 7). Peptide Vault's advantage is rating (5.0 vs 4.5) and review sentiment (100% vs 78%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Peptide Vault sells 11 in-app purchases, starting at $9.99 per month and Stackr sells 7 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Peptide Vault holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Stackr has 126 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 100% of Peptide Vault's written reviews are positive against 78% of Stackr's.

Peptide Vault ships an update weekly, Stackr every 3 days. The most recent releases landed on September 9, 2026 and September 22, 2026 respectively.
