# WP 34s vs RLM

The clearest difference is review sentiment: WP 34s at 93% against RLM's 53%. WP 34s also leads on in-app purchases (none vs 4) and ratings volume (29 vs 1). RLM's advantage is rating (5.0 vs 4.7) and update cadence (monthly vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. RLM sells 4 in-app purchases, starting at $0.49 per month. WP 34s asks for nothing beyond the download.

RLM holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: WP 34s has 29 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 93% of WP 34s's written reviews are positive against 53% of RLM's, so the app with the better star average is not the one people write more warmly about.

WP 34s ships an update every 4 months, RLM monthly. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
