Flow is a DNS privacy app for iPhone and iPad. It encrypts every DNS query your device makes — preventing your carrier, ISP, and anyone on your network from seeing which websites and services you use. WHAT DNS IS AND WHY IT MATTERS Every time you open an app or visit a website, your device first asks a DNS server to translate the address into an IP. By default, this request is sent unencrypted — visible to your carrier, ISP, and anyone monitoring your connection. Flow replaces this with DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT), encrypting every query so only the provider you choose can read it. HOW IT WORKS Flow installs a secure DNS profile directly on your device. Once active, every DNS request — every app, every website, every service — is encrypted before it leaves your iPhone or iPad. No VPN. No app that needs to stay open. No extra battery drain. 16+ PROVIDERS TO CHOOSE FROM • Cloudflare 1.1.1.1 — fastest public DNS, strict no-logging policy • Quad9 — blocks malware and phishing domains automatically • AdGuard — removes ads and trackers at the DNS level • NextDNS — fully customisable filtering rules • Mullvad — privacy-first, no logs, Tor-compatible • Google, OpenDNS, CleanBrowsing, Control D, and more Switch providers in seconds. Or add your own custom DoH or DoT server. FLOW+ — PAY ONCE, OWN IT FOREVER Flow+ unlocks the full experience with a single payment. No subscription. No renewal. No catch. Flow+ includes: • All privacy and ad-blocking providers • Custom DNS profiles — save up to 3 configurations • Auto-switch by network — different DNS per Wi-Fi • DNS Benchmark — find the fastest provider for your connection • DNS Health Check — resolution, latency, leaks, DNSSEC • Disconnect alerts — get notified if your profile goes offline • Siri & Shortcuts — pause, resume, switch providers by voice • Themes and accent colours • iCloud sync — settings follow you across all your devices • Lock Screen and Home Screen widgets YOUR PRIVACY Flow has no servers and no analytics. It does not log, collect, or sell any information about your DNS activity or browsing. The provider you choose handles your queries according to their own privacy policy — check it before you pick. Requires iOS 16 or later. Compatible with iPhone and iPad. ______________________________ IMPORTANT Privacy Policy: flowprivacy.rift.lat Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
