# DubFilter vs EQ

The clearest difference is update cadence: EQ at every 2 weeks against DubFilter's every 6 months. EQ also leads on review sentiment (90% vs 73%) and iOS requirement (10.0 vs 17.0). DubFilter's advantage is ratings volume (71 vs 20). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. DubFilter sells 1 one-off in-app purchase and EQ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for DubFilter against 4.8 for EQ. Both are backed by a comparable volume of ratings — 71 and 20 respectively. Written reviews are what separate them: 73% of DubFilter's written reviews are positive against 90% of EQ's.

DubFilter ships an update every 6 months, EQ every 2 weeks. The most recent releases landed on September 22, 2026 and August 20, 2026 respectively.
