ZoneSync: Make Time Work Across Timezones Working with people in different parts of the world often means dealing with confusing time conversions, scheduling conflicts, and missed meetings. Most productivity tools were built for a world where everyone worked in the same timezone. ZoneSync is designed to simplify how individuals and teams coordinate time across regions. Instead of switching between world clocks, calendars, and reminders, ZoneSync brings timezone comparison, scheduling, reminders, and contextual notes into one unified experience. Whether you're managing remote teams, working with international clients, or organizing meetings across continents, ZoneSync helps you plan with clarity and confidence. Key Features Compare Multiple Timezones View time across different regions side by side and easily understand how working hours overlap. Timezone-Aware Reminders Create reminders and meetings that stay accurate across locations and prevent scheduling mistakes. Visual Time Comparison Identify the best meeting windows without manual conversions or guesswork. Contextual Notes Keep important notes connected to specific locations or time references so information stays organized. Built for Global Collaboration ZoneSync supports the way modern work actually happens โ€” across countries, teams, and timezones. It helps remote teams, freelancers, and global organizations coordinate faster and reduce scheduling confusion. Plan meetings more confidently, avoid time conversion errors, and stay organized across multiple regions with ZoneSync.

See what time it is for every teammate right now โ€” and find the one hour that works for all of them before you send the invite. Most world clock apps stop at a list of cities. This one adds the part you actually need: each person's working hours. Give every city a name and a start/end hour, and the app turns that into a 24-hour ring, a live overlap arc, and a ranked list of the best times to meet. No mental math, no "wait, is that their morning?", no spreadsheet. WHAT YOU GET - Know instantly whether a colleague is at their desk or asleep, without asking - See the exact hours when everyone on the team is working, drawn as one glowing arc - Get a ranked shortlist of the best meeting hours, in UTC, for today or any of the next 6 days - Read a color grid of who is working across all 24 hours, so you can spot a compromise slot - Watch every city's clock tick live, with its UTC offset and today's date - Browse cities by region โ€” Americas, Europe, Asia, Pacific โ€” and add one in a tap PERFECT FOR - Remote and distributed teams running standups across continents - Freelancers and agencies juggling clients in other countries - Managers scheduling 1:1s without waking anyone at 3am - Anyone keeping in touch with family or friends living abroad WHY NOT JUST USE THE BUILT-IN CLOCK? The stock clock shows you times. It doesn't know that London stops at 17:00, that Tokyo starts at 10:00, or that your designer in Sydney is already offline. Working hours are the whole point โ€” they are what turns a wall of numbers into an answer. PRIVACY Everything stays on your iPhone. No account, no sign-up, no ads, no tracking, and nothing uploaded anywhere. The app works fully offline. FULL ACCESS Full access unlocks unlimited cities and team members, the live overlap ring, the meeting finder with its best-time ranking and 24-hour grid, and the city explorer. Choose the plan that suits you: weekly, yearly, or a one-time lifetime unlock (pay once, keep it forever). Prices are shown in your local currency before you confirm. Add your first three cities and see your team's overlap in under a minute.
