Touchscreen Pro vs WiFi Coverage Survey & Heatmap

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.

Where should the router go? WiFi Coverage Survey answers that by measuring, not guessing — with a coverage heatmap drawn over your own floor plan, a ranked report of every spot, and a separate internet speed test. Start a recording, walk your home, and name the spots you care about — the desk, the couch, the far bedroom. The app measures continuously while you walk and produces a report ranking every spot, so you can see exactly where coverage falls apart and which access point is responsible. WHY NOT JUST A SIGNAL BAR iOS does not give apps the raw signal strength, and even where it is available it is a poor predictor: Wi-Fi hides a weakening link behind retransmission, so everything looks fine right up until the connection collapses. WiFi Coverage Survey instead measures the things that degrade early — loss on large frames, TCP retransmission and failed connections, tail latency, throughput, and the negotiated PHY mode — and combines them into a single 0–100 score. WHAT YOU GET • A live score, dial and chart while you walk • Mark This Spot — captures the 10 seconds before you press, so typing a name never pollutes the measurement • A ranked table of every spot, best to worst • Per access point breakdown: which node served which part of the walk, so you know which one to move • Outage and handover detection • A floor plan you sketch yourself, with your marked spots on it and a coverage heatmap over the walls • Placement advice based on the recording • CSV and JSON export • History, so you can compare before and after moving the router INTERNET SPEED TEST A separate tab measures the line itself rather than the Wi-Fi: download and upload over parallel streams, idle latency and latency under load, and which Cloudflare edge is serving you. Runs are kept in a history on the device so you can compare them. Five tests a day. PRIVACY The survey is measured against your own router and stays on your device — nothing is uploaded. The internet speed test is the one exception: it exchanges traffic with our own test server, and only when you start it. Location permission is requested only because iOS will not reveal the Wi-Fi network name to an app without it — your location is never recorded or shared. NOTES Recording needs the screen on, because iOS does not allow Wi-Fi sampling in the background. Measurement is deliberately intensive, so expect noticeable battery use during a walk. The survey's throughput figure is relative to your own router and is not a measure of your internet connection — the speed test tab does that.
