A simple Clock/Information Interface made to take advantage of the iPhone OLED displays. Keep track of time, add a personal note, check the weather, add icons or images to the Information Interface. The interface takes minor jumps each minute (3 pixels), this is built as a safety measure for OLED panels. OLEDX is highly energy efficient. By using the most efficient methods to accomplish its main purpose OLEDX achieves very low power consumption. The iPhone OLED screens make it possible to have zero light emitting from pixels that are not being used, the entire screen will look completely dark while the information interface pixels will emit light. Features: -Display Time and Date -Current Weather Face -Display Battery Information -Display Icon or Personal Note -Display Icon -Dual Time Zone Interface -Analog Or Digital Clock -Proximity Sensor Monitoring -Energy Efficient -Multiple Watch Faces -Face color customization -Star Roofs -Adjust brightness of the interface by panning up and down across it. And more. Star roofs once set will go into a slide show mode and will loop through the set. This is done in order to prevent a single roof from being displayed for extended periods of time. The Settings button shows on and off when you first enter the app, but you can tap on that position of the screen anytime to access the settings menu. Screen brightness can be adjusted by panning up and down with your finger across the interface.

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!)

Verdict
The clearest difference is rating: OLEDX at 4.6 against OLED Clock's 3.9. OLEDX also leads on ratings volume (5.2K vs 15). OLED Clock's advantage is in-app purchases (none vs 1) and update cadence (every 4 weeks vs every 10 months). On price, ads and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. OLEDX sells 1 one-off in-app purchase. OLED Clock asks for nothing beyond the download.
OLEDX holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: OLEDX has 5.2K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 49% of OLEDX's written reviews are positive against 79% of OLED Clock's, so the app with the better star average is not the one people write more warmly about.
OLEDX ships an update every 10 months, OLED Clock every 4 weeks. The most recent releases landed on September 22, 2026 and September 20, 2026 respectively.
