A clock app built around one idea: open it, and the time stays on. No sleep settings to fiddle with. No timers to configure. The screen just keeps showing the time, from the moment you tap the icon. On the floor. In the booth. Backstage. Next to the camera. In the middle of a long meeting. For the moments when all you need is to see what time it is — clearly, continuously, without anything else getting in the way. ■ Simple Comes First No countdowns. No remotes. No cloud. No accounts. Buy it. Install it. Open it. Done. There is nothing to set up. ■ When You Need More, It's There ・Large timecode-style display (HH:MM:SS) ・5 fonts to choose from, including DSEG7 Classic (7-segment LED style) ・Free color selection (RGB / HSB) ・Tap the time to toggle 24-hour / 12-hour format ・Faint analog clock layered behind, with adjustable opacity ・Major city timezone presets, with automatic Daylight Saving Time ・Optional LAP stopwatch when screen space allows Every option fits on a single landscape settings panel. Adjust while watching the clock change behind it, in real time. ■ Design Principles ・Fully offline Zero network requests. Works without signal, works in studios with strict IT policies. ・No data collection No analytics. No tracking. No ads. No advertising identifier (IDFA). ・One-time purchase Buy once.
