Set the alarm time in just two seconds. This simple alarm clock app has been designed for maximum ease of use. Set your favorite music as your alarm and wake up happy! ALARM FUNCTIONS: - Snooze (3 - 30 minutes) - Vibration - Fade in alarm OTHER FEATURES: - Sleep timer (sleep music) - 12 hour and 24 hour time format - Vertical and horizontal modes MORNING: Use music of your choice or select one of the preset alarms to wake up happy and smiling. EVENING: Relax and fall asleep to the sound of your favorite song or one of the preset sleep music. APP FEATURES: Unique and intuitive interface is easy to use: launch the app and have your alarm ready in just two seconds. WHY WE DEVELOPED THIS APP: There are many alarm clock apps found on the App Store today. However, most of these require the user to tap through numerous screens just to set an alarm. Also, most of these apps use a built-in widget for the interface, making it hard to interact with them intuitively. If you find yourself regularly changing your alarm time, the existing apps out there are a real pain. That's why we developed this new app, which uses an analog clock for inspiration.

Zen Clock is a minimalist iPhone clock built around calm, legibility, and strong typography. Designed to work beautifully on a desk, nightstand, charging stand, or an always-nearby spare iPhone, it offers a full-screen time surface that never demands your attention. We intentionally avoided building a generic alarm, timer, or productivity app. Instead, Zen Clock’s promise is simple: make checking the time feel quiet, polished, and visually intentional. Signature Color Clock Modes Experience time as a living color, not just digits. Our signature Color Clock modes transform the current time into a shifting, live background gradient. Full Spectrum: Maps Unix time across the entire color spectrum. Day Mode: Maps the current day from midnight to night. Hour Mode: Maps the current hour from the top to the end of the hour. Curated Visual Themes & Typography Choose from seven striking visual themes, including White on Black, Black on White, White on Blue, Red on Black, and our signature Color Clock modes. Pair your theme with four distinct typographic styles (Zen, Rounded, Mono, and Serif) to make your clock feel airy, friendly, precise, or editorial. Composed for Your Space With our preview-first settings, you aren't just toggling options—you are composing a timepiece. Choose the layout that fits your environment: Pure: The ultimate minimalist experience. Time only. Calendar: Elegantly integrates the weekday and date. Editorial: A beautiful, designed asymmetric composition. Board: A restrained status surface that gracefully holds supporting information without overpowering the time. Supporting Context (Premium) For those who want a bit more at a glance, Zen Clock gracefully integrates extra details without the clutter. Add a curated World Clock rail to display up to two global cities (such as Los Angeles, New York, London, Paris, Tokyo, or Sydney). Access live local weather conditions and temperatures seamlessly integrated into your composed layout while the app is open. Home Screen Widget Bring a touch of Zen Clock to your Home Screen with our included minimal clock widget, featuring a stark black background, crisp white text, and our signature aesthetic.
