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. Lock orientation or apply a mirror effect for reflected setups. **Sound & Alerts** Hourly chime with configurable active hours and sounds. Completion alarms with haptics when your timer or pomodoro finishes. Spoken time always available for hands-free checks. **macOS Experience** One universal purchase. Pin the window to float above other apps, navigate with full keyboard shortcuts, and switch between sidebar or tab navigation. **Languages** English, 简体中文, 繁體中文, Français, Deutsch, Italiano, 日本語, 한국어, Русский, Español. Switch in-app without changing your system language. **Liquid Clock Pro** Unlock all backgrounds, fonts, colors, the widget, mirror effect, background running, target date timer, hourly chime, alternate app icons, iCloud sync, and more. Core clock, stopwatch, countdown timer, speak time, burn-in protection, and notifications are always free. No ads, ever.

Verdict
The clearest difference is in-app purchases: TetraClock at none against Liquid Clock's 3. TetraClock also leads on update cadence (every 2 days vs every 8 days) and iOS requirement (14.0 vs 26.2). Liquid Clock's advantage is ads (none vs shown). On price and device support there is nothing between them.
