# PeptidePal vs PepOS

The clearest difference is review sentiment: PepOS at 100% against PeptidePal's 30%. PepOS also leads on ads (none vs shown) and rating (5.0 vs 4.7). PeptidePal's advantage is ratings volume (4.9K vs 1) and update cadence (every 5 days vs fortnightly). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. PeptidePal sells 19 in-app purchases, starting at $3.99 per 7 days and PepOS sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

PepOS holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PeptidePal has 4.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 30% of PeptidePal's written reviews are positive against 100% of PepOS's.

PeptidePal ships an update every 5 days, PepOS fortnightly. The most recent releases landed on October 28, 2026 and October 15, 2026 respectively.
