Liquid Clock turns your device into a calm, immersive display for time, focus, and countdowns. Available on iPhone, iPad, and Mac. See the time at a glance with a bold flip-style clock, then switch into Pomodoro or timer mode when you need to focus. Liquid Clock is designed to feel beautiful on a nightstand, desk, or charging stand while still giving you the tools to stay on track. **Flip Clock** Large flip-style digits with smooth 3D card-flip animations. Choose between 12-hour and 24-hour formats, show or hide seconds, and add a date overlay in your preferred style. Two-finger long-press speaks the current time aloud. **Pomodoro Timer** Stay focused with configurable work sessions, short breaks, and long breaks. Set how many sessions before a long break, enable background running, and customize per-phase alarm sounds with haptics. **Timer & Stopwatch** Three modes for every need: stopwatch counts up, countdown timer counts back from any duration, and target date mode counts down to a specific moment — showing years, months, and days for distant events. **Customization** Make it yours with animated backgrounds — fluid blobs, silk lines, floating shapes, luster sheen, gradients, and solid colors. Pick from 17 digit colors, 5 fonts, and custom card backgrounds. Choose from multiple tick sounds and alternate app icons. **Widget** Add a flip clock widget to your Home Screen or Lock Screen in small, medium, or large. It mirrors your style settings and shows live seconds on the medium size. **Built for Comfort** Keep the screen on, auto-hide controls after inactivity, auto-dim for nighttime, and enable burn-in protection for OLED displays.
