Welcome to NeuroSmile
A gentle companion for recovering from Bell’s palsy or Ramsay Hunt syndrome.
Each day you’ll take a quick 1-minute check-in. The app compares how the two sides of your face move and shows you every bit of progress — even the small steps.
For most people, facial palsy gets better with time. Bell’s palsy often improves within weeks to months, and Ramsay Hunt syndrome usually takes longer. Every journey is different, and tracking helps you see the healing as it happens.
🔒 Your photos never leave this phone. No account, no uploads.
ℹ️ NeuroSmile is a tool to help you see potential progress. Its scores are estimates, not 100% accurate, and not a medical measurement.
Why a quick setup first?
Accurate tracking needs a starting point. Your start date and baseline photos give every future check-in something to compare against — that’s how NeuroSmile can spot even the smallest improvement and show you how far you’ve come.

About your recovery
Knowing your condition and start date lets us show which day you’re on and the kinds of milestones that are possible for you. A best guess is perfectly fine.
Which condition do you have?
Ramsay Hunt syndrome is caused by the shingles virus and often takes longer to recover from. You can change this any time in Settings.

Your baseline photos
This is the last setup step. Your baseline is the starting point every future check-in is measured against, so the more natural it is, the more accurate your progress will be.
You’ll be guided through four simple expressions:
- 😐 A relaxed face
- 😁 A big smile
- 😮 Raised eyebrows
- 😌 Eyes gently closed
For the best baseline: face a window or soft light, hold the phone at eye level about an arm’s length away, and go easy — never strain.
However your face looks today is perfectly okay. This is simply where your journey begins.

Your recovery journey
NeuroSmile is a tool to help you see potential progress. Scores are estimates and not 100% accurate. It is not a medical device or diagnosis. Follow your doctor’s advice. Seek urgent care for sudden weakness in an arm or leg, trouble speaking, or a severe headache.
How did you sleep?
How much sleep did you get last night? Rest plays a big part in healing, and tiredness can affect how your face moves.

Let’s relax first
Three slow breaths help your face muscles settle, so your photos show your true resting face. Recommended for the most accurate tracking.

Let your jaw drop slightly, your cheeks soften, and your forehead go smooth.

ℹ️ This score is an estimate to help you spot trends, not an exact or medical measurement. Lighting, camera angle and how you make each expression can shift it by a few points.

Overall symmetry over time
Tap a point to see that day. Higher is more symmetric. Scores are estimates, so look at the overall trend rather than any single day.
First check-in vs. latest (smile)

Privacy & how it works
Your photos never leave your phone
Face analysis runs entirely on this device. Photos and scores are saved in this app’s private storage on your phone only. Nothing is uploaded, and there is no account.
The only download is the face-analysis model itself, fetched once and then cached so the app works offline.
How accurate is it?
NeuroSmile is a tool to help you see potential progress over time. It is not 100% accurate and is not a medical measurement or diagnosis.
Phone cameras and face tracking are good at spotting changes, but scores can shift by a few points because of lighting, camera angle, distance, tiredness or how big each expression is. A single high or low score doesn’t mean much on its own. The trend over days and weeks is far more meaningful.
Only your doctor or a facial therapist can properly assess your recovery. Use NeuroSmile alongside their care, not instead of it.
How the score works
Each check-in asks for four expressions. For each one, the app finds 478 points on your face and compares how far your left and right side move. If your weaker side moves 70% as much as your stronger side, that movement scores about 70.
The overall score blends: relaxed face 20%, smile 35%, eyebrow raise 20%, eye closing 25%. 100 means both sides look and move the same. If an expression doesn’t show enough movement to measure, it’s left out rather than guessed.
Tips for steady numbers
- Check in at the same time and place each day.
- Face a window or soft light — avoid strong light from one side.
- Hold the phone at eye level, arm’s length away.
- Expect a few points of day-to-day wobble. Watch the trend.
Bell’s palsy and Ramsay Hunt syndrome
Both affect the facial nerve and can cause weakness on one side of the face. Ramsay Hunt syndrome is caused by the shingles virus and can also bring a painful rash in or around the ear, ear pain, or changes in hearing. Recovery from Ramsay Hunt syndrome usually takes longer, often many months, so be extra patient with yourself.
Whichever you have, your journey is your own. NeuroSmile shows possible milestones, not deadlines, and you can change your condition any time in Settings.
