# Understanding Devices Data

The Devices tab in Humblytics Analytics shows how visitors access your website across different operating systems, device types, and browsers. This helps you understand your audience's technology preferences and optimize your site accordingly.

**Accessing Devices Data**

1. Log in to your Humblytics account and select your site.
2. Click **Analytics** in the sidebar under **Analyze**.
3. Click the **Devices** tab in the top navigation.

**Summary Metrics**

At the top of the page, you'll see a quick overview:

* **Sessions** — Total number of sessions across all devices
* **OS** — Number of distinct operating systems detected
* **Devices** — Number of device categories (desktop, mobile, tablet)
* **Browsers** — Number of distinct browsers detected
* **Top OS** — The most common operating system among your visitors

**Donut Chart**

A visual donut chart displays the distribution of visitors by operating system (or device/browser, depending on the selected sub-tab). Each segment shows the percentage share, giving you an at-a-glance view of your audience's technology mix.

**Sub-Tabs**

The Devices page has three sub-tabs, each with a searchable table:

* **OS** — Breaks down sessions by operating system (e.g., iOS, Android, Mac OS X, Windows, Linux, Chrome OS). Shows the operating system name, session count, a visual share bar, and percentage.
* **Device** — Breaks down sessions by device category (Desktop, Mobile, Tablet). Helps you understand how visitors prefer to browse your site.
* **Browser** — Breaks down sessions by browser (e.g., Chrome, Safari, Firefox, Edge, Samsung Internet). Useful for ensuring cross-browser compatibility.

Each table includes:

* A **search bar** to filter results
* **Sessions** column showing the number of sessions
* **Share** column showing the percentage with a visual bar

**Using Devices Data**

Understanding your device breakdown helps you:

* **Prioritize responsive design** — If most traffic is mobile, ensure your mobile experience is excellent
* **Test across platforms** — Focus testing on your top browsers and operating systems
* **Identify trends** — Track shifts in device usage over time to stay ahead of user preferences
