ClockPhone is a stylish and functional clock app that’s easy to use. It features an advanced alarm with flexible repeat settings: by day of the week, on a specific date, or following a shift schedule. And to make sure you really wake up, there are not just standard options to turn it off, but also advanced methods — like scanning an NFC tag, QR/barcode (for example, on a toothpaste tube in the bathroom), or solving math problems. ClockPhone also includes a versatile timer, perfect for workouts — including various interval types like Tabata, and productivity techniques like Pomodoro, 52/17, and 90/30 — as well as for cooking, meditation, and any task that needs precise time control. The app combines a thoughtfully designed interface with a rich feature set. Thanks to its stylish and attractive time display, ClockPhone fits beautifully into any space. The large digits are easy to read from any distance, and the second hand comes with different display modes for enhanced readability. Time transitions are smoothly animated, and the clock’s appearance is easy to customize via a functional and intuitive interface. Perfect for use on a charging dock or for bringing new life to a favorite device. It looks great in both landscape and portrait orientations. An onboarding guide shows how to control the app with gestures.
