# PeptIQ vs Peptide Stack

The clearest difference is rating: PeptIQ at 4.7 against Peptide Stack's 4.2. PeptIQ also leads on ratings volume (944 vs 5) and iOS requirement (16.4 vs 18.0). Peptide Stack's advantage is update cadence (daily vs every 4 days). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. PeptIQ sells 12 in-app purchases, starting at $9.99 per 7 days and Peptide Stack sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

PeptIQ holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: PeptIQ has 944 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 65% of PeptIQ's written reviews are positive against 67% of Peptide Stack's, so the app with the better star average is not the one people write more warmly about.

PeptIQ ships an update every 4 days, Peptide Stack daily. The most recent releases landed on October 15, 2026 and October 2, 2026 respectively.
