No burn-In! This clock is perfectly suited for the OLED display in iPhone X, because the clock won't stand still on the screen but moves around constantly using any available pixel of the screen over time. Also it smoothly changes color over the complete color spectrum, so that every sub pixel (red, green, blue) will be used evenly. This prevents the so called "burn-in effect" any OLED display shows, if certain pixels are switched on for a very long time. The clock not just works on iPhone X but on all iOS devices like iPhone, iPod Touch and iPad (iOS 9.3 and above). But there's more: - NEW: digital and analog representation of the clock. You choose! - choose between a huge number of nice looking fonts to display the actual time - adjust clocks size just by using the pinch gesture on main screen - use automatic color changes "color cycling" (recommended on iPhone x, can be switched off in settings) - adjust the clocks brightness by using scroll up and down gesture on the main screen - tap on the main screen to show tab bar at the bottom of the screen, here you will be able to switch between analog and digital view, call settings, help and about page - on settings page you can change font, color and animation speed as well as switch on/off seconds, blinking separators, 24h display, autosize and color cycling - all adjustments are permanent! OLED clock remembers them on the next time you use it! - use OLED clock in portrait or landscape mode. On digital mode, OLED clock remembers your preferred font size depending on device orientation - help page provides necessary information about usage - fully localized in english, german, hebrew, french and japanese (new!)

ClockRadio is the new generation of the very first clock radio on the App Store. Wake up the way you like — to your radio, your Apple Music playlists or your podcasts — and gently, thanks to the discreet alarm. Developed with care, in France. NEW — Try everything, without an account Set an alarm as soon as you open the app: no account is required to be woken up. And during your five free alarms, nothing is restricted. Sleep timer, night mode, repeating alarms, waking through headphones or a speaker, gradual light: you try the entire app, not a version stripped of its best features. Main features • Wake up to your favorite radio station • Wake up to your Apple Music playlists • Wake up to your podcasts: follow your favorite shows and start the day with the latest episode • Discreet alarm: a soft first ring at reduced volume, then normal volume if you are still asleep. No more harsh awakenings! • Elegant, perfectly legible night mode — your choice: analog watch or digital display • The time you have left to sleep, shown large under the clock • Hour-by-hour weather, from the evening until the next day • Flashlight, one gesture away from the app's main screen • Home Screen widget: your next alarm, without opening the app • Sleep timer: fall asleep to your radio, your music or a podcast • Snooze, to enjoy a little longer • Ultra-reliable multiple alarms • Minimalist, intuitive interface • Eight color themes, including Sage and Fuchsia A night mode designed for three in the morning When you open your eyes in the dark, you want to know two things: what time it is, and how much time is left. ClockRadio shows both. The time remaining before the alarm appears under the clock, in large type, readable without glasses and without turning on the light. And if you fell asleep to the radio, the sleep countdown stays in view, and you can lengthen or shorten it by five minutes without leaving the screen. The weather for your night, and for your morning Hour by hour, from this evening until tomorrow, with a simple swipe of the finger. With an option nobody thinks of offering: hide the hours when you are asleep. The forecast then starts when you wake up, not in the middle of the night. A flashlight, designed for the night A button opens a completely black screen: nothing dazzles you just when you are looking for light. A bar sets the strength of the beam, from weakest to strongest, and your setting is kept. It turns itself off when you leave the app, and after two minutes without the phone moving. Your next alarm on the Home Screen The ClockRadio widget shows the time of your next alarm and its label, in small or medium size. A glance before going to bed is enough to check that everything is in place — without opening the app, without unlocking anything. NEW — Your alarms follow you Change phones, reinstall the app: your scheduled alarms are kept on your account. You sign in, and you choose what you want to do with them. They come back switched off, so that nothing rings without your consent. Stations added and checked by the people who listen to them. Type the name of a station: the ones other users have already added appear right away. Listen to it before adding it, to check it is the right one. And if it is still missing, request it — it will join the catalog as soon as we find its stream. Available offers • Free version: 5 alarms, all features unlocked • Lifetime offer: one-time purchase, no subscription, no renewal • Optional subscription: to support ongoing development and access new features Download ClockRadio and discover a modern, uncluttered, customizable and really cool clock radio — created with its community.
