# Shepherd vs Einstein AI

The clearest difference is review sentiment: Shepherd at 100% against Einstein AI's 20%. Shepherd also leads on rating (5.0 vs 4.6) and update cadence (every 5 days vs fortnightly). Einstein AI's advantage is ratings volume (193 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Shepherd sells 3 in-app purchases, starting at $6.99 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.

Shepherd holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Einstein AI has 193 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Shepherd's written reviews are positive against 20% of Einstein AI's.

Shepherd ships an update every 5 days, Einstein AI fortnightly. Both last shipped on October 24, 2026.
