# System requirements 

> See what Quo’s operating system (OS) requirements are for desktop, web, and mobile.

Quo works across desktop, web, and mobile. To make sure calls, messages, and features like [Sona](https://support.quo.com/core-concepts/ai-automations/sona/overview) run smoothly, your device needs to meet the following minimum requirements.

***

## Desktop app

If you’re using the Quo desktop app, your operating system must meet these minimum versions:

| Operating system | Minimum version     |
| ---------------- | ------------------- |
| macOS            | macOS 12 or later   |
| Windows          | Windows 11 or later |

***

## Web app

If you’re using Quo in a browser at [my.quo.com](https://my.quo.com/), these browsers are supported:

| Browser | Supported versions |
| ------- | ------------------ |
| Chrome  | Latest 4 versions  |
| Firefox | Latest 4 versions  |
| Safari  | 16.0 or later      |

Using an up-to-date browser make sure that features like [calling](https://support.quo.com/core-concepts/calling/making-calls), [texting](https://support.quo.com/core-concepts/messaging/overview), and [team messaging](https://support.quo.com/core-concepts/team-collaboration/team-messaging) work reliably.

***

## Mobile app

Quo’s mobile apps require the following operating system versions:

| Operating system | Minimum version    |
| ---------------- | ------------------ |
| iOS              | iOS 16.0 or later  |
| Android          | Android 8 or later |

Keeping your device updated helps prevent [call quality](https://support.quo.com/core-concepts/calling/call-quality-metrics) issues, crashes, and missing features.

## FAQs

<AccordionGroup>
  <Accordion title="What happens if I’m using an unsupported operating system or browser?">
    If your device or browser is below Quo’s minimum requirements, some features may not work correctly. You might see issues like poor call quality, missing features, or app crashes. Updating to a supported version usually resolves these problems
  </Accordion>

  <Accordion title="Will Quo still open if I’m on an older version?">
    In many cases, Quo may still open, but it isn’t guaranteed to work reliably. New features, security updates, and performance improvements are designed for supported versions, so using an outdated system can lead to unexpected behavior.

  <Accordion title="Do I need to update my device every time Quo updates?">
    No. You only need to make sure your operating system or browser stays within Quo’s supported versions. Keeping your device and browser up to date ensures you automatically get the best performance and compatibility with new Quo features
