# PeptidePal vs Biostacks

The clearest difference is ads: Biostacks at none against PeptidePal's shown. Biostacks also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 18.0). PeptidePal's advantage is ratings volume (4.8K vs 1) and chart position (#197 vs unranked). On price, update cadence, 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 Biostacks sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Biostacks holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PeptidePal has 4.8K ratings behind it against 1, so its average is the more settled of the two.

PeptidePal ships an update every 5 days, Biostacks every 10 days. The most recent releases landed on October 20, 2026 and October 6, 2026 respectively.
