# Peptides Calculator vs PepGuide

The clearest difference is rating: Peptides Calculator at 4.3 against PepGuide's 3.9. Peptides Calculator also leads on review sentiment (55% vs 33%) and update cadence (every 5 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Peptides Calculator sells 11 in-app purchases, starting at $9.99 per month and PepGuide sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Peptides Calculator holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Peptides Calculator has 173 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 55% of Peptides Calculator's written reviews are positive against 33% of PepGuide's.

Peptides Calculator ships an update every 5 days, PepGuide every 3 weeks. The most recent releases landed on October 12, 2026 and October 6, 2026 respectively.
