# iSoundex vs PlantWave

The clearest difference is price: PlantWave at Free against iSoundex's $0.99. PlantWave also leads on rating (4.3 vs 2.5) and update cadence (every 5 weeks vs every 72 months). iSoundex's advantage is in-app purchases (none vs 4) and iOS requirement (12.0 vs 15.6). On review sentiment, ads and device support there is nothing between them.

PlantWave is free to download; iSoundex costs $0.99 up front. PlantWave sells 4 in-app purchases, starting at $3.99 per month. iSoundex asks for nothing beyond the download.

PlantWave holds the better App Store score, 4.3 against 2.5. That said, the two scores are not equally well evidenced: PlantWave has 57 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of iSoundex's written reviews are positive against 65% of PlantWave's, so the app with the better star average is not the one people write more warmly about.

iSoundex ships an update every 72 months, PlantWave every 5 weeks. The most recent releases landed on June 1, 2026 and October 18, 2026 respectively.
