As a seasoned Android customization expert with years of hands-on experience testing keyboard apps, I've explored countless options to enhance user interfaces. Android offers endless customization possibilities, from invisible keyboards to lightning-fast shortcut layouts. Today, I'll walk you through Chrooma Keyboard, a standout app that dynamically shifts its background color to match the active app—creating a cohesive, immersive typing experience.

Among top Android keyboards, aesthetics often win out over raw features. A polished user interface truly elevates your daily interactions. Chrooma Keyboard excels here, blending beauty with functionality.


As shown, the keyboard's background adapts to the dominant color of your current app. This requires Android Lollipop (5.0) or later. Its clean layout echoes the familiar Google Keyboard design for easy transition.
Note: It doesn't integrate with system-default keyboards like Google's, which many devices ship with—it's built as a standalone powerhouse.
Layout tweaks, like adding a number row (surprisingly premium-locked), split mode, or collapse for one-handed use, unlock in the premium version. Originally paid, it's now freemium for broader access.


Chrooma's premium styling shines: default flat design upgrades to gradients and per-row color palettes. Customize fonts freely too.
Free users enjoy Night Mode, darkening the scheme based on the app—set it to trigger by time or always on. I keep mine perpetual for eye comfort.
Fix a single color system-wide, enable battery saver dimming, gesture typing, emoji predictions (rolling out soon), and premium multilingual support.
