# PeptidePal vs SpicyCalc

The clearest difference is ads: SpicyCalc at none against PeptidePal's shown. SpicyCalc also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 18.0). PeptidePal's advantage is ratings volume (4.9K vs 1). 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 SpicyCalc sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SpicyCalc 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.

PeptidePal ships an update every 5 days, SpicyCalc every 4 days. The most recent releases landed on October 28, 2026 and October 8, 2026 respectively.
