I'm in Beijing. My family is in Vancouver. I used to do the math on my fingers, or open the world clock twice. Now I turn the phone sideways onto the charging stand and both cities stand there side by side. I just look up. TWO CITIES, ONE SCREEN Two clocks, stacked or side by side, each on its own city's time. No more counting hours. FOUR LOOKS Flip, for the mechanical clack of a split-flap board. Glass, when you want it clean. City Day & Night, to see at a glance whether it's light over there. Single City, when you only care about one. WHAT'S THE WEATHER THERE Each clock carries the current conditions and temperature. Faster than asking "is it cold where you are?" IT DIMS WHEN IT GETS DARK THERE Night brightness follows the city on screen, not your phone. When it's night on their side, that half dims and the stars come out. Easy on the eyes at 3am. IT FINDS THE PLACE A built-in worldwide city database that also includes universities and high schools - search "Stanford University" and it's there. Anything missing is looked up online, and saved only if you pick it. Cities you use often float to the top. LOCK SCREEN AND HOME SCREEN WIDGETS Small, medium, large, extra large. The larger sizes show dates and weather for both cities at once. LANDSCAPE, ALWAYS ON The screen won't lock while the app is open - it's built to sit on a desk, a nightstand, a charging stand. Works in both landscape directions, so it's upright however you set it down. PRIVACY Location is optional. It's used only when you turn on GPS mode, to show the time and temperature where you are.

Red Dial Timer

Red Dial Timer turns time into something you can see. Inspired by the classic mechanical focus dial, a red wedge shrinks as your time runs out, so you always know how much is left at a glance, with no numbers to read. It's built for focus work, ADHD-friendly time awareness, studying, cooking, workouts, and anywhere a clear visual sense of time helps you stay on track. Most timers hide your time behind digits that you have to read, do the math on, and keep checking. Red Dial Timer shows it as a single shrinking shape, so the amount of time left registers instantly, the same way the classic desktop dials have helped people focus for decades, now on the device that's always with you. WATCH TIME DISAPPEAR The red sector sweeps down from the top as the minutes pass, with a moving hand at its leading edge. One look tells you where you stand, with no math and no squinting at a clock. As the red shrinks, your sense of urgency builds naturally, which is exactly what makes a visual timer so effective for getting started and staying with a task. BLOCK DISTRACTIONS WHILE YOU FOCUS Choose the apps and websites that pull you off task, and Red Dial Timer shields them automatically while your timer runs. The moment your session ends, pauses, or resets, everything unlocks again. There's nothing to remember to turn on and nothing to remember to turn off. You set your distractions once, and they're handled every session after that. Your choices stay private on your device, powered by Apple Screen Time, and the app never sees the names of the apps you pick. SET IT IN A SECOND Drag anywhere on the dial to set your time. No menus, no number pads, no fiddly pickers. Switch between a one-hour and a two-hour face depending on the task, whether that's a quick ten-minute reset or a long, deep work block. STAY ON TASK, EVEN IN THE BACKGROUND The timer stays accurate when you leave the app, switch to something else, or lock your phone. A clear, time-sensitive alert lets you know the exact moment time's up, even from the lock screen, so you can step away from the screen and trust that the timer has your back. DESIGNED TO BE CALM A clean, dark interface keeps the focus on your time and nothing else. A gentle synthesized alarm and a flashing finish make sure you never miss the end of a session, without a jarring or stressful sound. BUILT FOR THE WAY YOU ACTUALLY WORK Focus and deep work: run a session, block the noise, and protect your attention. ADHD and time blindness: make the passage of time visible and concrete, so "later" stops sneaking up on you. Studying and revision: keep study blocks tight and take honest breaks. Work from home: hold a meeting to time, or cap how long a task is allowed to take. Cooking and baking: glance at the dial across the kitchen without unlocking your phone. Workouts and intervals: time rounds, rests, and stretches at a glance. Kids and routines: give younger users a clear, fair sense of how much time is left. WHY A VISUAL TIMER WORKS Reading a clock is a small task in itself, and for anyone who struggles with time awareness, it's a task that's easy to skip. A shrinking shape removes that step entirely. You don't read the time, you simply see it, which lowers the friction of starting and makes it far easier to notice when a session is almost over. PRIVACY FIRST Your timer runs entirely on your device. App and website blocking is powered by Apple Screen Time and your selections never leave your phone. The app does not enumerate your installed apps and cannot read the names of what you choose to block. Notifications are scheduled locally and are never sent to a server. Whether you're powering through a focus block, managing ADHD time blindness, keeping study sessions tight, or timing a workout, Red Dial Timer makes every minute visible. Make your time impossible to ignore.
