iPhone

One tap to eject water from your speaker. Sweep tones to shake out dust. Plus a real-time spectrum analyzer, decibel meter, hearing test, and dead-pixel screen check. Phone Doctor turns your iPhone into a full hardware diagnostics and repair toolbox. Got a wet speaker after a swim? Earbuds full of pocket lint? A pixel that won't turn off? Phone Doctor has a tool for it. WATER EJECT & SPEAKER CARE • Speaker Drainage — A 30-second 165 Hz tone vibrates trapped water out of your speaker grille, the same technique used by Apple Watch's water-eject feature. • Speaker Cleaner — A 10–18 kHz frequency sweep that shakes loose dust, lint, and debris from speaker mesh. • Earbud Cleaner — Pulse-clean the left, right, or both drivers individually. Works with AirPods, EarPods, or any wired or Bluetooth headphones. SOUND DIAGNOSTICS • Decibel Meter — Real-time approximate SPL readings with a rolling history graph. Know exactly how loud your environment is — at the gym, at a concert, at the office. • Spectrum Analyzer — Studio-style real-time FFT (1024-point Hann window, log-spaced bands). See the frequency content of any sound around you. • Hearing Test — A pure-tone audiogram across 8 frequencies for both ears. Use it as a quick self-screening tool, save the result, and track changes over time. SCREEN & MICROPHONE • Dead Pixel Test — Cycle through full-screen solid colors to spot stuck or dead pixels before they get worse. • Microphone Test — Record up to 5 seconds and play it back to verify your mic is working. WHY PHONE DOCTOR • 100% on-device. Microphone audio is processed in real time and never recorded to disk, never uploaded, never shared. • No accounts. No analytics. No ads. No tracking. • One-time payment for Pro — no subscription, no recurring charges, no surprise renewals. • Works offline once unlocked. • Built for iOS: clean, fast, and dark-mode friendly. FREE VS. PRO Free: Dead Pixel Test, Microphone Test, Decibel Meter. Pro (one-time unlock): Speaker Drainage, Speaker Cleaner, Earbud Cleaner, Spectrum Analyzer, Hearing Test. Pro is a single non-consumable purchase. Buy it once, restore it on any device signed in to your Apple ID. SAFETY Speaker drainage and dust-removal tools play loud audio by design — please remove headphones and lower the volume around others before starting. The hearing test is a self-screening tool only and is not a substitute for a clinical audiogram or medical diagnosis. Got feedback or a tool you'd like added?
