# WP 34s vs RLM

The clearest difference is in-app purchases: WP 34s at none against RLM's 4. WP 34s also leads on review sentiment (93% vs 67%) and ratings volume (28 vs 7). RLM's advantage is update cadence (every 3 weeks vs every 4 months) and rating (4.9 vs 4.7). 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, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 28 and 7 respectively. Written reviews complicate that: 93% of WP 34s's written reviews are positive against 67% 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 every 3 weeks. The most recent releases landed on September 20, 2026 and October 19, 2026 respectively.
