# Pep AI vs Milligram

The clearest difference is ads: Milligram at none against Pep AI's shown. Milligram also leads on review sentiment (58% vs 36%). Pep AI's advantage is ratings volume (4K vs 475). On price, rating, update cadence and in-app purchases 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 Milligram sells 3 in-app purchases, starting at $17.49 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Pep AI against 4.7 for Milligram. That said, the two scores are not equally well evidenced: Pep AI has 4K ratings behind it against 475, so its average is the more settled of the two. Written reviews are what separate them: 36% of Pep AI's written reviews are positive against 58% of Milligram's.

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