DNS Benchmark+ vs Magnetic Sensor

DNS Benchmark+ finds the DNS resolver that genuinely performs best for you — on your current Wi-Fi, cellular, or VPN connection — by measuring what users actually experience, not just DNS reply speed. **What makes DNS Benchmark+ different** Most DNS tools only measure how fast a resolver replies to a DNS query. DNS Benchmark+ goes further: it measures the real endpoints those replies point to. If a fast resolver sends you to a distant CDN node, it's not actually fast for you. DNS Benchmark+ measures both, then ranks resolvers by what matters. **Comprehensive testing** • UDP, DNS-over-TLS (DoT), DNS-over-HTTPS (DoH), and DNSCrypt resolvers — all supported • Real CDN endpoint probing: TCP and TLS latency to actual IPs returned • Globally-representative CDN test domains • DNS latency, jitter, and P99 — not just averages • Concurrent testing of many resolvers simultaneously • Per-run history with iCloud sync across all your devices **Security & privacy diagnostics** • DNSSEC validation — confirms resolver validates signatures and blocks spoofed records • NXDOMAIN hijack detection — identifies resolvers that redirect failed lookups to ad pages • ECS detection — checks if resolver sends client hints for optimal CDN routing • Bogus record blocking — confirms resolver rejects invalid DNSSEC responses • Resolver identity via CHAOS and NSID queries **Configurable scoring** DNS Benchmark+ uses a weighted scoring system you can tune: • Endpoint speed (TCP/TLS latency to real IPs) • DNS speed (raw query latency) • Reliability (success rate, rcode quality) • Stability (jitter and P99 consistency) • Locality (geographic proximity of returned endpoints) Adjust weights in Settings → Score Weights and save custom presets. **Powerful and configurable** • Add any resolver: IPv4/IPv6, tls://, https://, sdns:// DNSCrypt stamps • Configure test domains, concurrency, timeouts, and probe depth • Per-category iCloud sync — control what syncs between your devices • Run history with export and iCloud sync • Share results as formatted text **Privacy** All DNS benchmarking runs on your device. DNS queries go directly to each resolver under test. Approximate geolocation uses ipinfo.io. Run history is stored locally and optionally in your private iCloud account.

Magnetic Sensor turns your phone's built-in magnetometer into three precise tools: • Compass — A live, tilt-compensated compass with cardinal direction (N/E/S/W) and adjustable magnetic declination so the needle points to true north, not just magnetic north. • Metal Detector — Set a baseline reading anywhere, choose Low/Med/High sensitivity, and feel haptic pulses that get stronger as the field deviates. Perfect for finding studs in a wall, screws under drywall, or rebar in concrete. • Field Logger — Record samples at up to 60 Hz, then export to CSV via the share sheet. Saved recordings stay in the app for replay or re-export. KEY FEATURES • Live X / Y / Z axis readings + total field magnitude • Tilt-compensated heading using the accelerometer • Magnitude history sparkline + multi-channel chart • Rolling statistics: mean, standard deviation, RMS, range • Figure-8 calibration helper with quality indicator • Min / Max tracking with one-tap reset • Three sample rates: Slow (500 ms), Normal (100 ms), Fast (16 ms) • Light / Dark / System theme • English and Korean • Unit options: μT, mGauss, nT • Adjustable smoothing • Magnetic declination presets • Haptic alerts for the detector • Keep-screen-awake while recording • CSV export with full timestamp + per-axis data PRIVACY All sensor data is processed on-device and never leaves your phone. The app does not collect location, contacts, or personal information. Anonymous mobile advertising is used to keep the app free; you can watch a rewarded ad to unlock unlimited CSV sharing for the session. WHO IT'S FOR • Hobbyists exploring magnetic fields • DIYers detecting screws, studs, and rebar • Students collecting data for physics or geology projects • Hikers wanting a reliable phone compass • Anyone curious about the invisible field around them REQUIREMENTS A device with a magnetometer (most phones built since ~2013). The app cannot work on devices without one — it will tell you on launch.
