## Description

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.
