Ziro: Binary Clock & Focus

Looking for a free Pomodoro timer with built-in white noise? Ziro is a Pomodoro timer, white noise app and binary clock in one — a minimalist focus app for deep work, study, sleep and meditation. A POMODORO TIMER FOR DEEP WORK AND STUDY Ziro is a clean, distraction-free Pomodoro timer for studying, coding and deep work sessions. Pick a work interval and a break interval — 25/5, 50/10 or your own — and start. Each Pomodoro session pairs with built-in white noise, so focus blocks arrive with a soundtrack. Use Ziro as a study timer for school, a work timer for deep work, or a tomato timer for quick concentration sprints. WHITE NOISE FOR SLEEP, STUDY AND FOCUS Ziro doubles as a full white noise app with brown noise, pink noise, rain sounds and ambient hum. Use white noise for sleep at bedtime, brown noise for deep focus, pink noise for studying, or rain sounds for a calmer meditation. Every sound loops cleanly offline — no buffering, no internet required. A BINARY CLOCK FOR THE TECH CURIOUS At its heart, Ziro is a binary clock — a minimalist clock that tells time in zeros and ones. Each column of dots is a digit; each dot is a power of two. The binary clock turns time-of-day into the same language your computer speaks, making it a conversation piece for developers, programmers, engineers, students and anyone who likes their gadgets a little more geek. 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.
