A focused touchscreen diagnostic for iPhone. Catch phantom taps, map unresponsive dead zones, then export a PDF report for an AppleCare claim or a resale listing — every test runs on-device.
Download on the App StoreBuilt for phone buyers, sellers, and repair techs who need to know if a screen is actually healthy.
iPhone ships no built-in touch test. Draw to map dead zones, leave the phone idle to catch ghost touches — the dedicated diagnostic Apple doesn't include.
Export a PDF report with a touch heatmap, pass/fail table, and device info. Bring it to the Genius Bar or attach it to a resale listing.
No accounts, no cloud, no tracking of your test data. Every diagnostic runs on your iPhone and works completely offline.
Each test targets one real-world touchscreen failure. Run one, or run them all for a single overall verdict.
30-second full-screen scan for coverage gaps.
Draw across the screen to map unresponsive areas.
Leave the phone idle to catch phantom touches (30 / 60 / 120s).
Count how many fingers register at once.

Verify long-press feedback and timing.
Test large-area contact handling.
Run every test in sequence for one verdict.
Three steps. A clear answer.
Open the app and choose a test from the dashboard — or run the Full Diagnostic to cover everything at once.
Draw across the screen, leave the phone idle, or tap along the edges. Each test takes seconds.
