# palmEM AI vs Bates' Pocket Guide

The clearest difference is rating: Bates' Pocket Guide at 4.8 against palmEM AI's 4.2. Bates' Pocket Guide also leads on ratings volume (301 vs 72). palmEM AI's advantage is review sentiment (82% vs 41%) and update cadence (every 3 weeks vs every 14 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. palmEM AI sells 5 in-app purchases, starting at $9.99 per month and Bates' Pocket Guide sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Bates' Pocket Guide holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 72 and 301 respectively. Written reviews complicate that: 82% of palmEM AI's written reviews are positive against 41% of Bates' Pocket Guide's, so the app with the better star average is not the one people write more warmly about.
