Touchscreen Pro vs NetMaster

Buying a used phone? Just had a screen repaired? Selling online? Can you actually prove it works? Touchscreen Pro checks, diagnoses and documents your phone's real condition. Instead of guessing, you drive the real device through a 200-point touch scan plus display, audio, sensor, camera and connectivity checks. Perfect for: - Checking a used phone before you buy - Verifying a screen repair or replacement - Proving condition for resale or trade-in - Investigating touch or hardware issues What you can test: - Guided touch scan (grid, 200 points) - Edge and corner touch check - Ghost touch detection (idle monitoring) - Multi-touch and gesture tests - Display check (dead pixels, burn-in) - Speaker, earpiece and microphone - Vibration, proximity, accelerometer, gyroscope - Front/rear cameras, flashlight, volume buttons - Battery, charging, biometrics (Face ID / Touch ID) - Wi-Fi, mobile data, Bluetooth, GPS Pricing: - Every test is free - Watch a short video ad to export a report for free - Pro (one-time purchase) removes ads and unlocks unlimited report export, history and custom templates - No subscription With Pro you also get: - No ads - Automatic A-D score - Saved history and before/after comparison - PDF report with a QR code Built to trust: - Every test runs fully offline - Your diagnostic data stays on your device Touchscreen Pro doesn't just "try" your phone. It helps you judge it and prove it. Pro: Monthly / Yearly / Lifetime Auto-renews until canceled. Cancel anytime in your App Store settings.

NetMaster helps explain slowdowns, instability, and intermittent dropouts without an account, ads, analytics, or tracking. RUN A COMPLETE NETWORK SCAN • Measure download and upload goodput with parallel HTTPS requests • See HTTPS latency, adjacent response-time variation, request failures, and a second latency vantage point • See confidence ranges and a p95 only when enough observations support it • Check direct UDP DNS response delivery across two providers, including bursts • Check latency under load and receive a bufferbloat grade • Compare everyday and first-time DNS response times • See the DNS transport observed for NetMaster’s measured request and compare resolver performance • Test real IPv4 and IPv6 reachability • Time the router hop and see whether added delay is local or farther upstream • Review public IP, ASN, egress region, TLS, HTTP, Wi-Fi security, captive-portal evidence, and tunnel indicators • Optionally install the bundled NetMaster Shortcut for connected iPhone Wi-Fi channel, standard, RSSI, noise, and RX/TX PHY rates — no compatible router or controller required • Watch live signal/noise, negotiated PHY rates, passive device traffic, and access-point changes • Compare the OS route gateway, Apple, Cloudflare, Google, and selected public-service latency graphs, rotating one probe at a time • Optionally select an M-Lab server for a separate single-flow route cross-check NARROW DOWN CONNECTION PROBLEMS Quick Diagnosis checks the path, router, internet, DNS, and responsiveness in sequence, then gives one likely explanation and a practical next step. INVESTIGATE INTERMITTENT DROPOUTS Run a 5-, 15-, or 30-minute monitor. On iOS 26, a user-started finite session can request lock-screen continuation; earlier versions must keep NetMaster visible. NetMaster records route changes, HTTPS heartbeats, gateway/DNS controls, IPv4/IPv6 evidence, latency changes, unknown gaps, and optional AP-roaming evidence. ESTIMATE ACTIVITY NEEDS Cautious assessments cover calls, 4K streaming, gaming, browsing, and uploads while naming the measured evidence and its limits. Protected history compares the same network over time, with a metrics-only mode. WATCH YOUR MAC FROM IPHONE Pair one iPhone to your Mac through private iCloud. See processor, memory, thermal, battery, and Mac traffic updates, 30-day history, eligible alerts, and PDF/CSV reports. Storage and low-storage findings remain visible only on the Mac. Remote speed tests require confirmation. BUILT FOR HONEST RESULTS A payload budget controls data use. Replenished parallel transfers target a stable window; when the cap ends a fast test too soon, the result is a lower bound, not a claimed maximum. Full-scan HTTPS timing is not ICMP ping; the separate live-latency board uses explicitly labeled ICMP echo. HTTPS adjacent response variation is not packet jitter; HTTPS request failures and UDP DNS response loss are not raw packet loss. PRIVACY BY DESIGN History stays in protected on-device storage. Optional Mac monitoring uses your private CloudKit database and no developer monitoring server. Reports leave only when you choose Share, with address redaction on by default. Important: Direct iOS app APIs omit exact radio values. The optional user-installed Shortcut uses Apple's Get Network Details action for connected RSSI, noise, channel, standard, and PHY rates; derived band can be ambiguous. Channel width, RF spectrum health, and cellular dBm are never invented. Wi-Fi identity needs permission. Balanced allows about 54.5 MB of throughput payload plus small requests and protocol overhead. Results are evidence, not proof that a router, carrier, VPN, or service is defective.
