About

GPF Bubble Level

Read full description

GPF Bubble Level is a minimal, high-contrast spirit level app for iPhone, built around real-time accelerometer data. It uses Core Motion to read device gravity and translates movement into a smooth on-screen bubble inside a circular level grid. The interface is intentionally clean: black background, white elements, Menlo typography, and a compact layout designed for quick visual alignment in everyday use. Key features: - Real-time level detection using accelerometer/device motion - Smooth bubble movement with light filtering for stability - Tilt angle readout in degrees - Live X/Y gravity values for reference - Dedicated Info screen with app icon, title, and version/build footer - Custom monochrome app icon (white on black) consistent with the app style Design goals: - Fast glanceability - No clutter - Strong visual contrast for indoor/outdoor visibility - Coherent monochrome identity across UI and iconography Technical notes: - SwiftUI-based UI - CoreMotion integration via observable motion manager - Motion privacy usage description configured - Build/version shown directly from bundle metadata This app is ideal for quick leveling checks on surfaces, shelves, frames, and small DIY tasks, with a focused UX that prioritizes readability and responsiveness.
