Just launched on the App Store
The right time zone, right when you need it.
Stop converting time zones in your head. ZoneFlow's widget automatically shows the right time zone at the right time of day — set it once, it just works.
Free on iOS · No account needed
Your day doesn't have one important time zone.
It has several, at different times. World clock apps show you a wall of clocks and leave the hard part to you — figuring out which one matters right now.
How it works
Set it once. That's the whole trick.
1.Tell it what matters
Pick your time zones and when you care about them. London in the morning, Tokyo in the evening.
2.It keeps up with your day
The widget switches automatically as the day goes on. Nothing to open, nothing to tap.
3.Glance, and know
Home Screen or Lock Screen — the right time is just there.
Who it's for
For the people your day revolves around.
Family & friends far away
Know when it's a good time to call Mom.
Without opening a converter, without counting hours on your fingers. When someone you love lives an ocean away, ZoneFlow quietly keeps their time in view — so staying close takes no effort at all.
Remote workers & distributed teams
Your teammate's morning, at a glance.
Standup in Berlin, review in New York, a question from Singapore. ZoneFlow shows the time that matters for the part of the day you're in — no matter where your team is.
Frequent travelers
It adapts as you move.
Land, look at your Lock Screen, and know. Local time, home time, the office back east — the widget follows your schedule, so you're never left wondering which clock is which.
Not another world clock.
Most clock apps show more — more clocks, more cities, more data. ZoneFlow shows less: the one time that matters right now.
Less a clock app, more a quiet assistant.
FAQ
Fair questions.
Isn't this just a world clock app?
No — it doesn't show everything at once. It shows the one time you need, automatically, based on your schedule.
Is the free version actually usable?
Yes. Unlimited time zone changes within your schedule and a full widget — not a stripped-down trial.
A note from the maker
I built ZoneFlow out of a small, persistent frustration: I cared about different time zones at different times of day, and I was tired of juggling them in my head. Mornings meant one city, evenings another — and every world clock app just showed me everything, all the time.
So I made something that solves one problem well. You tell it your rhythm once, and it quietly keeps up. I hope it makes your far-away people feel a little closer.

One glance. The right time. Always.
