Big Display & Infinite Themes
Free · In-App Purchases
Simple, beautiful, and easy to read. Stunningly large characters fill the screen. Easily create your own personalized clock with infinite customization combinations.
Looking for a clock that's actually easy to read?
That's exactly why I built Infinite Clock.
Big, bold numbers that fill your entire screen. Beautiful colors that catch your eye. A clock so clear you can read it from across the room—while cooking, studying, or just glancing over from your couch.
But it's not just about visibility. It's about making it yours.
I've spent over 10 years refining this app. It became the No.1 clock app in Japan with over 2 million downloads. Now I'm excited to share it with the world—and I hope it becomes your favorite clock, too.
【 Why Infinite Clock? 】
● See the time from anywhere.
Time is displayed using the entire screen with massive, bold characters. No squinting, no leaning in. Just a quick glance from across the room, and you know exactly what time it is. Perfect for your desk, kitchen, bedroom, or workout space.

- Saved Presets: Created the perfect look? Save it. Switch between your "Focus Mode" clock and "Relax Mode" clock with a single tap.
【 A Note from the Developer 】
I created Infinite Clock with one simple belief: the easiest-to-read clock is the most beautiful clock.
Over the years, I've added feature after feature—not to make it complicated, but to make it adaptable. Whether you need a sharp, high-contrast display for work, a calming photo background for your bedside, or a reliable timer in the kitchen, Infinite Clock is ready.
The combinations are truly infinite. And that's the point.
I built this to be the definitive clock app—the one that stays by your side for years. It has the reliability of a utility tool, but the warmth of something personal.
I hope Infinite Clock finds a place on your desk today.
more The Saved Clocks manager has been completely redesigned with a brand-new card-based grid layout!
What was once a plain list is now a collection of visual cards showing each clock's actual background, font, and colors. No more opening clocks one by one just to remember how they look — find the one you want at a glance and switch instantly.
A new segment control at the top lets you toggle between your landscape and portrait collections. It defaults to match your device's current orientation, and a handy status indicator always tells you which set you're viewing.
Reordering now has its own dedicated screen. Color bars give you a quick visual reference for each clock's theme, and simple drag handles make rearranging smooth and intuitive — keeping the main grid clean and focused.
More refinements are on the way. Have thoughts or ideas? Drop us a line through the in-app support email — we'd love to hear from you.

The background image manager has been completely rebuilt from the ground up — with a more visual, more intuitive experience!
[Grid View for Your Image Collection]
Your background images are now displayed in a sleek grid layout. Each thumbnail shows a preview of your clock font overlaid on the image, so you can see exactly how it'll look. The grid adapts automatically when you rotate your device.
[A Brand-New Crop Tool]
Image cropping has been rebuilt from scratch. Pinch to zoom, drag to reposition — it's smooth, responsive, and feels completely natural. The area outside your crop is gently dimmed so you always know exactly what you're keeping. A quick tips overlay appears on first use to help you get started.
[Compare All Filters at a Glance]
Color and blur filters are now shown in a grid with instant previews. See every option side by side and pick the one that's just right — no more guessing.
[Easier Reordering]
Rearranging your background images is now as simple as grabbing a handle and dragging it up or down.
[Background Image Guide]
A new help screen answers common questions like why images are separated by orientation and how cropping works.

The font and color theme picker has been completely redesigned — it's now more fun and easier to use than ever!
[Card-Style Grid Preview]

[Smarter Filtering]
New filtering options let you quickly narrow down to just your favorites, hidden items, or user-added colors. Finding the perfect font or color theme has never been easier.
[Better Ad Experience]

The app now features iOS 26's Liquid Glass design — everything has a brand-new look!
[Liquid Glass Design]
The entire app has been updated with iOS 26's Liquid Glass. Navigation bars, toolbars, and menus now use translucent glass materials that let backgrounds show through. Combined with the icon redesign from the previous update, the whole app feels noticeably more modern.
[Better Dark Mode Visibility]
A dedicated accent color for Dark Mode has been added. Buttons and text now stand out clearly on dark backgrounds, making nighttime use more comfortable.
[Improved Dynamic Type Support]
Support for iOS text size settings (Dynamic Type) has been thoroughly improved. Everything displays properly even at larger text sizes.
[Unified Toolbar Buttons]
Toolbar buttons now use SF Symbol icons throughout, making each action easy to recognize at a glance.

Mugen Clock's alarm feature just got a massive upgrade — fully rebuilt around the powerful new alarm system introduced in iOS 26!
[Alarms That Ring Through Silent Mode]
Previously, alarms were delivered as notifications, which meant they wouldn't make a sound when your iPhone was in silent mode. That's no longer the case. On iOS 26 and later, Mugen Clock's alarms are treated as true system-level alarms — they break through both silent mode and Focus mode, every time. No more worrying about oversleeping because you forgot to turn the ringer on.
[Snooze Countdown on Your Lock Screen]
When you hit snooze, a real-time countdown appears right on your lock screen so you always know exactly how many minutes you have left. On devices with Dynamic Island, snooze info stays visible at the top of your screen. You can pause, resume, or dismiss the alarm directly from the lock screen.
[Custom Snooze Duration Per Alarm]
You can now set a different snooze interval for each alarm — anywhere from 1 to 15 minutes. Keep it short for your morning wake-up call, or stretch it out for a quick power nap. You can also turn snooze off entirely for alarms that need to be non-negotiable.
[Full Compatibility with iOS 18 and Earlier]
This update brings a brand-new experience for iOS 26 users, but if you're on iOS 18 or earlier, everything continues to work just as before. When you do upgrade, your existing alarm settings transfer automatically — no setup required.
Exciting things are coming to Mugen Clock. Have thoughts, ideas, or feedback? We'd love to hear from you — reach out anytime through the support email in the app.

[Localization Infrastructure]
Translation data management has been unified under a modern format, enabling faster and more consistent multilingual improvements in future updates.

Every detail has been refined to ensure English-speaking users enjoy a more intuitive and seamless experience.

【Improved Offline Behavior & Update Frequency】
Thank you for using Mugen Clock. Building on the previous update, I have further enhanced the logic for acquiring weather information.
[Improved Startup Behavior] I have significantly improved how the app behaves when it cannot access a network or location data upon launch. The app now handles situations much better where signals are unavailable, such as inside tunnels or while on an airplane, ensuring a smoother display experience even without a connection.
[Optimized Frequency for Premium] In response to many requests, I have also improved the weather update frequency for Premium users, allowing for more timely information.
[A Note from the Developer] I believe that accurate and appropriate weather display is a crucial factor in the Mugen Clock experience. If you notice anything unusual or have any issues, please feel free to contact me at any time via the in-app support email.
5.60.2 10 Jan
【Overhauled Weather Logic & Battery Optimization】
Thank you for using Mugen Clock. This update brings a major overhaul to how weather information is acquired and displayed on the main screen.
Optimized Weather Acquisition I have rebuilt the internal logic for fetching weather data from the ground up. This optimization delivers several key benefits:
Reduced battery consumption
Lower network data usage
Improved overall app stability
Better Recovery on the Go With these improvements, the app recovers more smoothly after temporary signal loss. For example, if you lose GPS or network connection while driving through a tunnel, the correct weather information will reappear much faster once the signal is restored.

If you have any questions or notice anything while using the app, please feel free to contact me at any time via the in-app support email.

【Fahrenheit (°F) Support & Smart Defaults】
Thank you for using Mugen Clock. This first update of 2026 brings a highly requested feature to improve the experience for our global users.
Fahrenheit Support Based on your feedback, you can now switch the temperature unit between Celsius (°C) and Fahrenheit (°F). This allows you to check the weather intuitively in the unit you are most familiar with. You can change this option at any time by double-tapping the clock screen to open the "Customize Menu," then selecting the "Date, Day, Weather" section.
Smart Defaults When creating a new clock, the app now automatically selects the appropriate unit (Celsius or Fahrenheit) based on your device's region settings. This smart detection eliminates the need for manual adjustment, ensuring a seamless and optimized experience right from the start.
New Year's Greetings Happy New Year! I am committed to making Mugen Clock even better and more useful for your daily life throughout 2026. Thank you for your continued support.

【Expression Updates & Layout Fixes】
Thank you for using Mugen Clock. This update includes layout fixes based on user feedback and internal maintenance to improve stability.
App Store Primary Language Change I have changed the App Store's primary language to US English.
If your device is set to a language other than Japanese, you will now see all store content (screenshots, descriptions, etc.) in English by default.
There is no change for those using Japanese settings.
Improvements & Layout Fixes Based on user feedback, I have updated content in both Japanese and English. Specifically, I have fixed layout issues that were occurring in the English version to ensure a cleaner look.
Library Updates for iOS 26.2 I have updated third-party libraries to their latest versions to ensure full compatibility and stability with iOS 26.2.

【Adjustments to Weather Updates for New Year's】
Thank you for using Mugen Clock. This update includes adjustments for the upcoming New Year countdown to ensure app stability.
■ New Year's Weather Updates As we approach the New Year countdown, I anticipate heavy traffic on the weather information server. To maintain stability, the frequency of weather updates will be temporarily adjusted during peak hours.
The adjustment period will be from around the countdown until 1:00 AM on New Year's Day.
Premium users are exempt from this adjustment and will continue to receive updates at the normal frequency. Normal update frequency will automatically resume after 1:00 AM.
■ Feedback on Localization I am committed to improving the English experience for the app. If you have any comments or suggestions regarding the English translation, please feel free to let me know. I will address them as a top priority.
Thank you for your continued support.
5.58.3 22/12/2025
[English Store Content & Localization Fixes] Thank you to all my English-speaking users for your valuable feedback. In this update, I have focused on fixing translation issues and fully localizing the App Store experience.
Localization Fixes I resolved an issue where the selected days of the week in the Alarm settings were still displaying in Japanese. I also fixed other dynamic text elements throughout the app that were not being translated correctly.
Full English App Store Page Starting with this update, I have fully localized the App Store content. Screenshots, descriptions, and other store details will now appear entirely in English for users in English-speaking regions.
Commitment to Quality I carefully review every piece of feedback I receive and am committed to prioritizing these fixes to provide a high-quality, fully localized experience.
If you notice any other missing translations or issues, please feel free to contact me anytime via the in-app support email. I will handle them as a top priority.
