# WeMorse vs RST Decoder

The clearest difference is rating: RST Decoder at 5.0 against WeMorse's 4.0. RST Decoder also leads on ratings volume (7 vs 1). WeMorse's advantage is ads (none vs shown) and review sentiment (100% vs 67%). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

RST Decoder holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: RST Decoder has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of WeMorse's written reviews are positive against 67% of RST Decoder's, so the app with the better star average is not the one people write more warmly about.

WeMorse ships an update every 5 weeks, RST Decoder every 2 months. The most recent releases landed on October 7, 2026 and October 6, 2026 respectively.
