Grail vs GPF Bubble Level

Grail watches for your screen. Grail turns the watches most of us only dream about into clock widgets you’ll actually use. On your Home Screen, on your nightstand in StandBy, and on your dashboard in CarPlay. It started simple: a collection of widgets based on wrist and pocket watches that offer an interesting design, are hard to get your hands on, or both. Every face is drawn with real horological detail, and built to be customized. Swap handsets, bezels, case metals, dials and colorways until it’s unmistakably yours. THE COLLECTION • Model One: Hours and minutes, inspired by Dirty Dozen field watches • Orbital Regulator: Hours, minutes and weekday orbiting the minute axis • DS-9000: Vintage digital display with time, day and date • Retro²: Jumping hour with retrograde minute, inspired by speedometers …and the collection keeps growing. WORKS ACROSS YOUR DEVICES • Home Screen & Desktop: Small and large sizes for your iPhone, iPad and Mac • StandBy: A proper bedside clock when your iPhone’s on its side • CarPlay: A mechanical dial on your dashboard MADE TO TINKER Broad Arrow or Dauphine hands. Stainless, titanium, DLC or gold. Pumpkin, Lime, Grape or Blueberry. Mix it however you like.

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.
