# Flow vs PetDNS

The clearest difference is rating: PetDNS at 5.0 against Flow's 4.4. Flow's advantage is update cadence (weekly vs every 3 weeks) and ratings volume (14 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Flow sells 3 in-app purchases, starting at $2.99 per month and PetDNS sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PetDNS holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Flow has 14 ratings behind it against 2, so its average is the more settled of the two.

Flow ships an update weekly, PetDNS every 3 weeks. The most recent releases landed on October 8, 2026 and October 20, 2026 respectively.
