# Supported Devices & System Requirements
ReadTheory is a web-based reading platform. You don’t need to install an app — students and teachers can use ReadTheory on supported devices with an internet connection and a compatible browser.
### Supported devices
ReadTheory is designed and optimized for:
- **Chromebooks**
- **iPads and Android tablets**
- **Desktop and laptop computers** (Windows, macOS, ChromeOS)
**Phones:** ReadTheory may load on phones, but the student experience is **not optimized for small screens**. For best results, we recommend using a tablet, Chromebook, or computer.
### Supported browsers
We support the latest versions of:
- **Google Chrome** (recommended)
- **Apple Safari**
- **Microsoft Edge**
The following browsers are **not officially supported**:
- **Internet Explorer (IE)**
- **Firefox**
- **Opera**
If you’re having trouble, first make sure you’re using one of the supported browsers and that it’s fully up to date.
### Minimum requirements
To use ReadTheory smoothly, you’ll need:
- A **stable internet connection**
- A supported browser (see above) with:
- **JavaScript enabled**
- **Cookies enabled**
- **Local storage enabled**
- **Audio support** (speakers or headphones) for the optional Read Aloud feature
### School network & filtering notes
If you’re using ReadTheory on a school network, please allowlist:
- **readtheory.org**
- **readtheory.com**
- **readtheoryapp.com**
- **All subdomains** of the above
Blocking cookies, JavaScript, or local storage can prevent ReadTheory from working properly.
### Accessibility
ReadTheory supports **screen readers** and common browser accessibility tools such as zoom and text scaling.
### Troubleshooting quick checks
If something isn’t working:
1. **Refresh the page**
2. **Confirm you’re using a supported browser**
3. **Update your browser** to the latest version
4. **Disable extensions** that may interfere (ad blockers, script blockers)
5. **Clear cache/cookies** and sign in again
6. If on a school network, try another network to confirm whether filtering is the cause
