Ziro
Read full descriptionHide full description
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.
Pomo Easy

Pomo Easy is a plain, exact Pomodoro timer: a dial, a headline that says what’s happening, and a single button. Twenty-five minutes on, five off, and a long rest once you’ve done four. Change any of it. WHY PEOPLE KEEP IT • It never drifts. Pomo Easy keeps the end time, not a ticking counter, so locking the screen, a restart or a clock change can’t stretch a session. • It reaches you. Session alerts are Time Sensitive and arrive with the app closed, in a sound you pick. • It reads at a glance. The top of the screen says “12 minutes of focus left” or “Long break”, and a bar shows how far into the cycle you are. LOCK SCREEN, HOME SCREEN, WRIST • A Live Activity and Dynamic Island countdown. • Widgets that roll over to the break by themselves, on your Home Screen or beside the clock. • On Apple Watch: whatever the iPhone dial is doing, with start, pause, skip and reset a tap away. PLAN THE HOUR • Attach a task and Pomo Easy tallies each finished session against it. Remove a session from History and the tally follows. • History shows today, the past week, your run of days and your strongest day. • On iPhone Duo, unfold for the whole cycle beside the dial. MAKE IT YOURS • Focus from 5 to 90 minutes, breaks from 1 to 60, two to eight sessions per cycle, and optional auto-start for breaks or focus. • Background noise for deep work: white, pink, brown, rain, café or ocean waves, still playing when the iPhone locks. • Eight accents, and the app icon changes to match. Dark mode comes in Graphite or Black. NOTHING LEAVES YOUR PHONE Pomo Easy has no sign-in, no ads and no trackers. Sessions, tasks and settings are kept on this iPhone only.

Verdict
The clearest difference is update cadence: Pomo Easy at every 10 days against Ziro's every 2 months. Ziro's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
