# BinHexDec vs CIDR

The clearest difference is ads: CIDR at none against BinHexDec's shown. CIDR also leads on update cadence (every 3 weeks vs every 115 months) and monetization model (free vs free with in-app purchases). BinHexDec's advantage is ratings volume (6 vs 1). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. BinHexDec sells 1 one-off in-app purchase and CIDR 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 BinHexDec against 5.0 for CIDR. That said, the two scores are not equally well evidenced: BinHexDec has 6 ratings behind it against 1, so its average is the more settled of the two.

BinHexDec ships an update every 115 months, CIDR every 3 weeks. The most recent releases landed on October 5, 2026 and October 11, 2026 respectively.
