Read full description

Simple, powerful, and customizable. This all-in-one clock app combines Alarm, Timer, and Stopwatch functions into a clean, intuitive interface. Privacy-friendly: When headphones are connected, the alarm sounds only through the headphones, not the device speakers. By making advanced features optional, we maintain a minimalist design while meeting a wide range of user needs. [General] Customization: Color themes, "My Theme" creation, and adjustable font sizes. Typography: Choose from system fonts, specialized clock fonts, or even add your own custom fonts. Time Display: Toggle between 12/24-hour formats, customize 12:00 vs. 0:00 display, and enable/disable leading zeros (e.g., 09:00 vs. 9:00). [Clock] Dual analog and digital display with extensive layout options. Design: Multiple dial designs and support for custom image/video backgrounds. Visibility: Toggle seconds, choose second hand movement (Ticking vs. Smooth), and customize date formats/languages. Dynamic Layout: Hide the status bar, tab bar, or settings button for a cleaner look. Digital-only mode available in landscape orientation. Hourly Chime: Use simple presets or create a fully customized hourly schedule. World Clock: View multiple cities and time zones simultaneously in a convenient list. [Alarm] Set unlimited alarms with full background notification support. Compatible with AlarmKit (iOS 26.1+), allowing alarms to sound even in Silent or Focus modes. Scheduling: Powerful repeat options including daily, weekly, monthly, yearly, and custom intervals (e.g., every 2 days). Supports pause periods. Sound: Use custom recordings or local music files (when the app is in the foreground). Management: Organize alarms with folders, label search, and easy duplication. Sort by time or firing order. Advanced Features: Checklist, Snooze, Auto-stop (by duration/repetition), Skip next, and one-tap global pause. New alarms can automatically inherit previous settings for faster setup. [Timer] Run multiple timers simultaneously ranging from 1 second to 10000 hours. Quick Start: Access presets and history for instant activation. Interface: Switch between list and full-screen views. Choose between 10-key or picker input with customizable units (1s/10s/1m/10m). Foreground Features: Displays estimated completion time and supports auto-stop for sounds. [Stopwatch] Records: Capture lap times with precision. Export: Send your recorded data as a text file via email. [Other Settings] System Integration: Audio mix mode (play alongside other music apps), and Auto-lock. Display: Brightness adjustment with "Darkness Correction" and customizable UI elements (toggle between switches or checkboxes). Note on Music: Currently, this app does not support playback for Apple Music, iCloud-only songs, or purchased songs that have not been downloaded to the device storage.
