# Mimir vs Atom AI

The clearest difference is ads: Mimir at none against Atom AI's shown. Mimir also leads on ratings volume (128 vs 1) and review sentiment (60% vs 50%). Atom AI's advantage is rating (5.0 vs 4.6) and iOS requirement (15.1 vs 26.1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mimir sells 2 in-app purchases, starting at $12.99 per month and Atom AI sells 3 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

Atom AI holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Mimir has 128 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Mimir's written reviews are positive against 50% of Atom AI's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 10 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
