# Ka vs SoundBox

The clearest difference is rating: Ka at 4.0 against SoundBox's 3.3. Ka also leads on in-app purchases (none vs 1) and iOS requirement (9.3 vs 12.0). SoundBox's advantage is review sentiment (50% vs 25%) and ratings volume (38 vs 6). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. SoundBox sells 1 one-off in-app purchase. Ka asks for nothing beyond the download.

Ka holds the better App Store score, 4.0 against 3.3. That said, the two scores are not equally well evidenced: SoundBox has 38 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 25% of Ka's written reviews are positive against 50% of SoundBox's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
