# Storing user device types

If you want more granular device type data to be stored (e.g. mobile/tablet/desktop or Android/iOS/Windows/MacOS) and used to filter sessions, you can manually store extra device data for each session using [Tags](https://docs.uxwizz.com/api/tags).

{% hint style="info" %}
Note: The device type is sometimes hard to define, for example nowadays laptops can have a touchscreen or tablets can have keyboards and mouse and be used as laptops, the so called 2-in-1 devices (e.g. Microsoft Surface).
{% endhint %}

You should include this script tag **after** the included UXWizz tracking snippet.

{% code title="Store device type as tag" %}

```html
<script>
(function() {
// Generic function to get device type based on UA string
function deviceType() {
    const ua = navigator.userAgent;
    if (/(tablet|ipad|playbook|silk)|(android(?!.*mobi))/i.test(ua)) {
        return "tablet";
    }
    else if (/Mobile|Android|iP(hone|od)|IEMobile|BlackBerry|Kindle|Silk-Accelerated|(hpw|web)OS|Opera M(obi|ini)/.test(ua)) {
        return "mobile";
    }
    return "desktop";
};

// Store the device type as a tag, e.g. "device-mobile"
UST.addTag('device-' + deviceType());
})();
</script>
```

{% endcode %}

{% hint style="info" %}
By default UXWizz does store the device type in the `ust_clients` table under the `device-type` column, but only stores `0` for desktop devices and `1` for mobile devices (no difference is made for tablets).
