# Peptides Calculator vs Pepdex

The clearest difference is review sentiment: Pepdex at 100% against Peptides Calculator's 55%. Pepdex also leads on rating (5.0 vs 4.3). Peptides Calculator's advantage is ratings volume (175 vs 6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Peptides Calculator sells 11 in-app purchases, starting at $9.99 per month and Pepdex sells 4 in-app purchases, starting at $5.00 per 7 days. Whichever you choose, the download price is not the number that matters.

Pepdex holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Peptides Calculator has 175 ratings behind it against 6, 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 100% of Pepdex's.

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
