# Notology vs Einstein AI

The clearest difference is rating: Einstein AI at 4.7 against Notology's 3.6. Einstein AI also leads on ads (none vs shown) and ratings volume (184 vs 31). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Notology sells 5 in-app purchases, starting at $9.99 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, 4.7 against 3.6. That said, the two scores are not equally well evidenced: Einstein AI has 184 ratings behind it against 31, so its average is the more settled of the two.

Notology ships an update fortnightly, Einstein AI every 2 weeks. The most recent releases landed on September 20, 2026 and September 2, 2026 respectively.
