Verdict
The clearest difference is price: SoundEcho at Free against CardsAlone's $0.99. SoundEcho also leads on update cadence (every 5 weeks vs every 18 months) and review sentiment (100% vs 83%). CardsAlone's advantage is in-app purchases (none vs 1) and rating (4.7 vs 4.3). On ads and device support there is nothing between them.

SoundEcho is free to download; CardsAlone costs $0.99 up front. SoundEcho sells 1 one-off in-app purchase. CardsAlone asks for nothing beyond the download.
CardsAlone holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: CardsAlone has 62 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 83% of CardsAlone's written reviews are positive against 100% of SoundEcho's, so the app with the better star average is not the one people write more warmly about.
CardsAlone ships an update every 18 months, SoundEcho every 5 weeks. The most recent releases landed on October 10, 2026 and September 25, 2026 respectively.
