# Feynman AI vs Einstein AI

The clearest difference is review sentiment: Feynman AI at 80% against Einstein AI's 20%. Einstein AI's advantage is ads (none vs shown) and rating (4.6 vs 4.4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Feynman AI sells 5 in-app purchases, starting at $5.99 per 7 days and Einstein AI sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Einstein AI holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Einstein AI has 192 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 80% of Feynman AI's written reviews are positive against 20% of Einstein AI's, so the app with the better star average is not the one people write more warmly about.

Feynman AI ships an update monthly, Einstein AI fortnightly. The most recent releases landed on November 8, 2026 and November 4, 2026 respectively.
