About this app

Experience the web the way it was meant to be seen. Umbra is a premium, beautifully crafted Safari Web Extension that brings a gorgeous, dynamic OLED dark mode to every single website you visit on your iPhone and iPad. Whether you are reading articles late at night, browsing forums, or just love the aesthetic of True Black, Umbra intelligently analyzes websites in real-time to invert colors seamlessly while preserving your photos, videos, and graphics perfectly. FEATURES: • Seamless Dark Mode: Turn any blindingly white website into a comfortable, deeply rich dark experience in Safari. • Real-time Intensity Slider: Fine-tune your dark mode from a soft slate gray to a deep, battery-saving OLED pitch black. • Warmth & Sepia Filters: Reduce eye strain and blue light exposure with a draggable warmth slider perfect for late-night reading. • Per-Site Customization: Enable or disable Umbra on specific websites natively from your Safari address bar. • Lightning Fast: Built entirely for iOS 15+ using Apple's native extension architecture for zero browser slowdown. Umbra respects your privacy. All color translation mathematics happen locally on your device, meaning your browsing history and data never leave your screen. Unlock the full Premium experience to customize your sliders on every website and lock in your permanent dark aesthetic.

Introducing a new Monthly Subscription option! We've also updated our premium paywall to make upgrading smoother, and made minor improvements to ensure a faster, more seamless Safari dark mode experience.
