See the time at a glance. Turn your iPhone or iPad into a large, full-screen clock for your desk or nightstand, with no ads or account required. START FREE Use the Digital clock with the Midnight appearance. Adjust the size, show the date or seconds, and choose 12-hour or 24-hour time. MAKE IT YOURS WITH CLOCK PRO Clock Pro is an optional one-time purchase, not a subscription. Add the Flip and Focus clock styles, Paper and Night Red appearances, and your own text, background and colon colors. Choose another time zone and give its displayed location your own town and country name. Add a personal message with its own font, size and color. Save up to five color settings, five messages and five time zones to switch between. QUICK TO ADJUST Tap a quick control to select its size slider. Tap again to cycle through its choices, or touch and hold to open its menu. Lock the controls to prevent accidental changes. A short interactive guide helps you get started. AT YOUR PACE Keep the screen awake while the clock is open. Burn-In Protection gently moves the display over time; it does not guarantee against screen burn-in. Keeping the screen awake uses more battery. Your personal messages, saved places and clock preferences are stored on your device, not collected by the developer. No account, ads or tracking. GOOD TO KNOW The app must stay open to show the clock; system restrictions may apply. Locking the controls does not lock the device or prevent leaving the app. World time shows one selected time zone at a time, and a custom place name does not use your physical location. Editing current settings does not overwrite a saved preset. The clock works offline; purchases and restoration use Apple's services. There are no alarms, timers, widgets or system Lock Screen replacement.
