WP 31s is a classic RPN scientific calculator based on the powerful but more complex WP 34s. Now available on iOS too (see the support site for other emulators and for the real stuff). It is not programmable but has a rich function set for daily use and is easier to use, thanks to a less cluttered keyboard.

Verdict
The clearest difference is update cadence: GmPasswords at every 5 months against WP 31s's every 10 months. WP 31s's advantage is ratings volume (15 vs 3) and iOS requirement (12.0 vs 14.1). On price, rating, review sentiment and ads there is nothing between them.
