How to Enable Dark Mode in OneNote on iOS: Reduce Eye Strain in 4 Simple Steps

If you spend evenings taking notes on your iPhone or iPad, OneNote’s bright white interface can strain your eyes. The solution is simple: enable dark mode on iOS, and OneNote instantly adapts to a darker theme that’s much easier on your eyes and perfect for late-night note-taking sessions.

What is Dark Mode in OneNote?

Dark mode is a display setting that inverts OneNote’s interface colors to create a darker, easier-on-the-eyes viewing experience. On iOS devices, OneNote automatically follows your device’s system-wide dark mode setting—there’s no separate dark mode toggle inside the app itself. This means when you enable dark mode in iOS Settings, OneNote adapts instantly, reducing blue light exposure during evening note-taking sessions. The entire OneNote interface, including your notebooks, notes, and all UI elements, transitions to dark colors. This feature is available on iOS 13 and later, aligning with Apple’s introduction of system-wide dark mode to iPhones and iPads. [Current as of: iOS 17, OneNote for iOS 2024]

Why Use This Feature?

• Reduces eye strain during evening work: Dark backgrounds are gentler on your eyes, especially in low-light environments like bedrooms or libraries during study sessions, making extended note-taking sessions more comfortable
• Supports better sleep patterns: Lower blue light exposure helps prevent disruption to your sleep schedule when you work on your device before bedtime
• Extends battery life on OLED displays: iPad models with OLED screens (iPad Pro models) use less power when displaying dark colors, giving you more time between charges
• Creates visual consistency across your device: OneNote matches your iOS system settings, so you get a cohesive experience across all your Apple apps without visual jarring between different applications

Things to Consider Before Enabling Dark Mode

• Requires iOS 13 or later: Dark mode only works on newer iOS versions released in 2019 or later; older iPad 2 or iPhone models running iOS 12 or earlier cannot use this feature
• OneNote follows your system setting only: You can’t customize dark mode within OneNote itself—it automatically mirrors your iOS dark mode setting, so you’ll need to adjust iOS Settings if you want to change the appearance later
• App-wide change affects all content: Enabling dark mode changes your entire OneNote experience including note content, so all your notebooks, notebooks, and notes will display in the dark theme with no exceptions

1. Unlock your device and open the Settings app Tap the Settings app (gray icon with white gears) on your home screen. This is where all your iOS system preferences live.

2. Navigate to Display & Brightness settings Once Settings opens, scroll down through the main menu. Look for Display & Brightness (you’ll usually find it between ‘Screen Time’ and ‘Accessibility’ in the list). Tap it to open the display settings.

3. Select Dark under the Appearance section In Display & Brightness, look for the Appearance section near the top. You’ll see three options: Light, Auto, and Dark. Tap the Dark option to enable dark mode immediately. The change takes effect instantly.

4. Open OneNote to see dark mode in action Close the Settings app and open OneNote from your home screen or App Library. Your notes, notebooks, the sidebar, and the entire interface will now display in dark colors. No additional settings need to be changed within OneNote itself—it automatically follows your iOS dark mode selection.

Whether you’re studying late at night, taking notes in dimly lit classrooms, or simply prefer a darker interface, this simple change keeps your productivity flowing while protecting your vision and maintaining consistency across all your iOS apps.
