Time, told in ones and zeros. Calm, delivered in soft hiss and rain. Ziro is a tiny piece of digital art that hides a binary clock and a white-noise machine inside one quiet screen. Open it on your desk while you work, set it by your bed while you sleep, or just leave it glowing on a spare phone as ambient room decor. No accounts, no ads, no nagging notifications — just zeros, ones, and the sound of focus. A BINARY CLOCK FOR THE TECHNICALLY CURIOUS Every column of dots is a digit; every dot is a power of two. Ziro turns the time of day into the same on/off language your computer speaks, making it an instant conversation piece for developers, engineers, students, and anyone who likes their gadgets a little geekier. Glance at it for a second and you get the time. Stare at it for a minute and you start to feel the pattern. It is the kind of clock that quietly teaches you something every time you check it. A FRIENDLY WAY TO LEARN BINARY Ziro doubles as a tiny lesson in how computers actually count. Watching the dots light up and reset teaches place value and powers of two more naturally than a textbook diagram. It is handy for students learning binary numbers for the first time, parents looking for a simple computer science explainer for kids, teachers wanting a visual aid, or anyone brushing up before a coding interview. There are no quizzes and no lessons to complete, just a clock that happens to explain itself. A POMODORO TIMER WITH WHITE NOISE BUILT IN Ziro pairs a classic Pomodoro work-and-break regime with a built-in sound machine, so deep work sessions arrive scored. Pick an interval, hit start, and let the soft hiss of white, pink, or brown noise mask office chatter while the binary dots quietly count down. Swap in rain, wind, or steady ambient hum to soothe a restless mind at bedtime, soundtrack a morning meditation, or help a baby drift off. Everything runs offline, so the soundscape never stops to buffer. A MINIMAL DESIGN, MADE AS AN ART PROJECT Ziro started as a small art project about how little a clock really needs to be. The result is a stripped-back interface with no menus to learn, no streaks to keep, and no dashboards to optimize. Just light, time, and sound — composed to feel calm on a nightstand and at home on a standing desk. Pick a color, dim the dots, and let the room change around it. FREE FOREVER, POWERED BY DONATIONS Ziro is completely free, with no subscriptions, no paywalls, and no advertising. If the app earns a spot in your daily routine, an optional donation inside the app keeps it independent and helps fund the next quiet feature. Download it, share it with the nerd in your life, and turn any screen into a small piece of moving art. Less interface. More time. Ziro. Ziro is free to download.

Verdict
The clearest difference is in-app purchases: Ziro at none against 10K Timer's 1. Ziro also leads on ads (none vs shown) and update cadence (every 2 months vs every 9 months). On price, device support and iOS requirement there is nothing between them.
