# App Launch Detection

{% hint style="info" %}
You'll need to import the javascript file in your website before starting from this [link](https://docs.webtonative.com/javascript-apis/getting-started).
{% endhint %}

This function returns `true` only when the app is launched. On subsequent calls during the same session, it will return `false`. If the app is terminated and relaunched, it will return `true` again. This behavior can be used to execute specific actions every time the app is launched.
