Description by Gian Paolo Fontani Written by the developer, not by AppBrain. Click to read.
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.
