# Pep AI vs Pepdex

The clearest difference is review sentiment: Pepdex at 100% against Pep AI's 36%. Pepdex also leads on ads (none vs shown) and rating (5.0 vs 4.7). Pep AI's advantage is ratings volume (4K vs 6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pep AI sells 16 in-app purchases, starting at $3.99 per 7 days 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 4.7. That said, the two scores are not equally well evidenced: Pep AI has 4K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 36% of Pep AI's written reviews are positive against 100% of Pepdex's.

Pep AI ships an update every 6 days, Pepdex every 5 days. Both last shipped on October 31, 2026.
