How To Use SmartCheck™

SmartCheck™ from Children’s TYLENOL® is a personal otoscope (ear scope) and app that turns your smartphone into an otoscope. The free* app will help guide you in how to correctly attach the device, position your child, take a recording of their eardrum, and send it to a healthcare provider. The SmartCheck™ device works in the same way as the otoscope your healthcare provider uses. The in-app prompts and patented guidance feature will help you capture a recording of your child’s eardrum.

How To: Step-by-Step

Step 1

Download and set up the SmartCheck™ app

Follow the in-app guidance to learn how to safely set up and use your SmartCheck™ device. Setup is simple and may take about 15 minutes.

Step 2

Install the battery

Using a small (size #000) Phillips-head screwdriver, loosen the side screw. Note that it’s not removable. Tilt the battery door toward the button to release the screw. Remove the battery door and insert the included alkaline AAA battery.

Step 3

Attach and align the device

How-to videos and in-app instructions will help you correctly align the device with your smartphone’s main camera and securely attach the device to your phone.

Step 4

Practice taking a recording

You’ll need a second person to complete the setup practice video. To get more comfortable using the device, you may want to practice recording an eardrum on another adult, an older child, or even your younger child when they’re feeling healthy.

Step 5

Take a recording

In the app, open your child’s profile, tap the ‘Attach / Record’ button, and follow the in-app prompts to take a clear recording of your child’s eardrum, assisted by our patented guidance feature.

Step 6

Review your recordings

Review your recordings to ensure they capture the entire eardrum. A healthcare provider needs a clear view of the eardrum to assist in their diagnosis. The app includes an example eardrum recording to help you learn what to capture in your recording.

Step 7

Share with a healthcare provider

Receive expert care 24/7 from the comfort of your home. Share your recordings with your healthcare provider or a telemedicine provider to assist them in providing a remote diagnosis.
