Egao: Daily Smile Tracker

FEATURES OF EGAO
Egao supports you in reaping the scientifically proven benefits of smiling. It automatically detects your smiles, tracks your daily streak, displays positive affirmations, and sends timely reminders to help you build a healthy daily habit.

• Automatic Smile Detection
Egao uses smart on-device face detection to automatically count and time your smiles—solo or together with friends—without manual logging.

• Daily Streaks & Detailed Statistics
Build momentum with your daily smile streak. Track your session history, daily averages, total duration, and personal records over time.

• Affirmations While You Smile
Combine the power of smiling with positive self-talk. Read built-in or custom affirmations right on screen while you smile.

• Smart Reminders
Consistency is key to well-being. Schedule gentle daily reminders for mornings, weekdays, or weekends whenever it fits your routine.

• Own Your Data (100% Local & Private)
Your well-being data belongs solely to you. All smile data and optional smile pictures stay strictly local on your device—no cloud servers, no accounts, and no external tracking. Export your data anytime as an SQLite database or CSV spreadsheet.

SCIENCE-BACKED BENEFITS OF SMILING
Smiling elevates mood, relieves stress, strengthens immune function, and increases pain resilience.

• Elevate Mood (Facial Feedback Effect)
We smile when we are happy, but research shows smiling itself makes us feel happier. A 2019 meta-analysis of 138 studies [1] confirmed that smiling—even intentionally—activates neural pathways that improve emotional well-being [2].

• Relieve Stress
Taking a short break to put on a smile helps lower stress responses and cortisol levels [3], helping you feel calmer throughout the day.

• Support Immune Health & Reduce Pain
Smiling triggers the release of endorphins—your body’s natural painkillers [5]—while relaxing neurotransmitters support immune function [4].

DISCLAIMER
Although smiling has many scientifically proven benefits for mental and physical health, Egao does not replace treatment by a qualified healthcare professional in the case of illness.
