# Feynman AI vs Einstein AI

The clearest difference is update cadence: Feynman AI at every 6 days against Einstein AI's every 2 weeks. Einstein AI's advantage is ratings volume (184 vs 50) and iOS requirement (15.1 vs 18.6). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Feynman AI sells 7 in-app purchases, starting at $2.99 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.

On the App Store both sit at effectively the same score — 4.6 for Feynman AI against 4.7 for Einstein AI. Both are backed by a comparable volume of ratings — 50 and 184 respectively.

Feynman AI ships an update every 6 days, Einstein AI every 2 weeks. The most recent releases landed on August 29, 2026 and September 2, 2026 respectively.
