# DubFilter vs Claravox

The clearest difference is review sentiment: DubFilter at 73% against Claravox's 0%. DubFilter also leads on ratings volume (71 vs 3). Claravox's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 6 months). On price and ads there is nothing between them.

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

Claravox holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DubFilter has 71 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 73% of DubFilter's written reviews are positive against 0% of Claravox's, so the app with the better star average is not the one people write more warmly about.

DubFilter ships an update every 6 months, Claravox every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
