## What is Phone Checkup?

Phone Checkup tests your phone or tablet from top to bottom.
It walks you through the screen, touch, sound, cameras, buttons and charging one step at a time, so anyone can finish a full check in about 3 minutes.

WHEN TO USE IT
- Right after buying a used iPhone or iPad, while the warranty or return period lasts
- Before selling, to confirm everything works and attach the results
- After a drop, or whenever something feels off

FREE CHECKS (8 ITEMS)
- Screen (dead pixels, burn-in)
- Touch (response all the way to the edges)
- Speakers (bottom and earpiece)
- Microphone
- Cameras (every lens)
- Buttons and vibration
- Charging
- Face ID / Touch ID

BEFORE YOU BUY
A checklist of what to look for on the price tag (SIM lock, battery maximum capacity, warranty and return rules) and which screens to ask the seller to show you.

RESULTS AS ONE IMAGE
Save or share one image with the model, OS, storage, date and a pass/fail mark for each item (watermarked in the free version).

DETAILED TESTS (one-time purchase, or watch one video ad to use it once)
- Clean result image without watermark
- Speaker buzz sweep
- Heat, throttling and battery drain (5 minutes)
- Touch sampling rate (Hz)
- Color and brightness uniformity
- Sensors (accelerometer, gyroscope, compass, proximity)
The one-time purchase unlocks everything with no time limit and removes ads. Use "Restore Purchase" when you change devices.

THINGS AN APP CANNOT READ
Battery maximum capacity, parts and repair history, and Activation Lock cannot be read by apps. The app shows you where to find them in Settings.

Results are stored only on your device and are never sent anywhere.
