# Re vs BiasProof

The clearest difference is update cadence: BiasProof at every 2 months against Re's every 13 months. BiasProof also leads on device support (3 vs 1). Re's advantage is ratings volume (10 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Re sells 3 one-off in-app purchases and BiasProof 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 — 5.0 for Re against 5.0 for BiasProof. That said, the two scores are not equally well evidenced: Re has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Re ships an update every 13 months, BiasProof every 2 months. The most recent releases landed on October 3, 2026 and October 1, 2026 respectively.
