Smile for your well-being



Smiling has a myriad of benefits, and the smile doesn’t even have to be real. Egao is a mobile app that helps you reap those benefits to live a healthier and happier life.

Benefits of smiling

Just to name a few: smiling, e.g., elevates mood, relieves stress, boosts the immune system, and reduces pain.

Elevate mood

We smile when we are happy. But did you know that we also become happy when we smile? This phenomenon is known as the facial feedback effect. A 2019 meta-analysis [1] of 138 studies verified its moderate but significant impact on happiness. Even fake smiling activates pathways in your brain that put you in an emotionally happy state [2].

Relieve stress

If there is one thing there is too much of in today’s world - it is stress. Stress influences how we feel, look, and interact with others (mostly not for the better). Taking a short break and putting on a smile helps you decrease your stress level [3]. You and your surrounding will benefit from it.

Boost the immune system

Smiling can also strengthen your immune system. Immune functions seem to improve because it relaxes you due to the release of neurotransmitters [4]. A simple smile can contribute to your overall health.

Reduce pain

Smiling releases endorphins, which are our body’s natural painkillers. When smiling, we are better prepared to deal with pain than otherwise [5].

Features of Egao

Get Statistics

Get all the stats you desire about how often and how long you smile.

See your averages and records and try to smile today more than yesterday.

Set Reminders

Consistency is key. Just one smile every other day will not change much. Especially when the intervention is so small as a smile, it is easy to forget about it. Egao helps you to be consistent and smile regularly with freely customizable reminders. 

Own your Data

We consider smiling as a minimal intervention for your well-being and mental health. Consequently, we consider all collected data as personal and help you to keep it private. All smile data is stored only locally and there is no data transfer to any server (we don't even have one).

Still, it is your data and you can do with it whatever you like. So, you can export your data as an SQLite database or as an easily readable spreadsheet.

Track your Smiles

Egao is smart (at least somewhat). Thanks to a locally run artificial neural network, it detects your smiles and automatically counts and times them for you.


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