I'm tired of mental math when finding time for the call across multiple timezones. You too? Great news, I've made an app for that! It's not for everyone, if you have all the team in google calendar – that's a great perk! But if you have calls with people outside of your organization and can't see their calendar, the alignment in messages or on the call becomes a pain in the... back. That's why Time Zone Slider is a visual tool to convert time for international meetings, clients abroad, travel, and family around the world. Time Zone Slider is what it says on the tin – it shows all your time zones side by side as you drag. No math, no guessing, no daylight saving surprises. Perfect for remote teams, international calls, and anyone tired of Googling "what time is it in Tokyo." Home screen widgets are available too. Add one and check world times at a glance. --- WHAT IT DOES - Drag the time drum and watch all zones update in real time - Color-coded working hours so you can see who's available at a glance - Spot the overlap — find the window where everyone is actually online - One tap to create a calendar event (Apple or Google) with timezone handling done for you - Copy all times as clean text to paste into Slack, email, or a message - Home screen widget — check times without opening the app --- WHO IT'S FOR Remote teams. Freelancers with clients abroad. People with family in other countries. Anyone who has ever Googled "UTC+5 to EST" and wished there was a better way. --- Built by one person, used by real humans. If something feels off, reach out — I read every message. --- Apple Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Zonal is a beautifully crafted world clock for people who live, work, and connect across time zones. Whether you're scheduling a call with a client in Tokyo, checking in on family in London, coordinating with a remote team in New York, or planning a trip to São Paulo — Zonal makes it effortless to know what time it is, anywhere in the world, at any moment. Your world, on one screen. Add any city from over 100 destinations worldwide, or choose from all 50 US states and Washington DC. Each location appears as a sleek card showing the local time, date, timezone abbreviation, UTC offset, and a live day-progress bar that visualizes exactly where in the 24-hour cycle that place currently sits. A time-of-day phase label — Dawn, Morning, Afternoon, Evening, Night, or Late Night — tells you at a glance whether your contact is starting their day or winding down for the night. Slide through time. Zonal's timeline slider lets you move forward or backward up to 12 hours and watch every city on your list update simultaneously. Finding a meeting window that works for everyone has never been simpler. See the overlap, pick the time, and get on with your day. Set any time, any city. Tap the time display on any card to set a specific local time for that city using an elegant iOS-style wheel picker. Dial in the exact hour and minute and Zonal instantly converts it across every location on your list — accounting for timezone offsets and daylight saving rules automatically. Need to pin a specific date and time? Use the built-in date and time picker to lock in any moment, past or future. Daylight saving, handled automatically. Zonal applies daylight saving rules for every location based on the exact date you're viewing. Scroll forward to November and watch US cities shift back an hour. Jump to summer in Australia and see the southern hemisphere DST come into effect. A clear DST badge on each card tells you when a clock has shifted so there are never any surprises. Reorder your world your way. Press and hold the drag handle on any card to pick it up and move it to exactly where you want it. A smooth floating preview follows your finger while a gold indicator shows precisely where the card will land. Designed to be enjoyed. Zonal ships with two refined themes — a deep dark mode with warm gold accents for night-time use, and a light parchment mode that's equally premium in daylight. Your preference is saved automatically. Every detail, from the serif clock numerals to the hairline progress bars and the gentle animations, has been considered as part of a cohesive, considered design. Zonal isn't just a utility you reach for reluctantly. It's an instrument you'll actually enjoy using.
