About
DeltaClock is a stylish world clock and time zone meeting planner built for people who work across multiple time zones. If you collaborate with teammates, clients, friends, or family in different countries, DeltaClock helps you compare cities, convert time zones, and schedule meetings without guesswork.
A WORLD CLOCK YOU CAN MOVE THROUGH TIME
Most world clock apps only show “now”. DeltaClock lets you scroll time forward or backward to preview any moment:
• Add your key cities and instantly compare local time in each time zone
• Scrub the timeline to answer “What time will it be there?” in seconds
• See day and night changes, date rollovers, and time differences visually
• Reduce mistakes during daylight saving time changes (DST)
TIME ZONE REMINDERS THAT MAKE SENSE
Create reminders based on the time in another city, and DeltaClock converts it to your local time automatically.
• Schedule reminders for calls, deadlines, lessons, streams, and flights
• Set reminders by “their time” (for example 9:00 in New York) and avoid mental math
• Great for distributed teams, freelancers, and international routines
OVERLAP PLANNER FOR REMOTE TEAMS
DeltaClock is also a meeting planner: it shows overlap windows across multiple time zones so you can pick a time that works for everyone.
• View overlaps for multiple cities in one planner
• Build plans from overlap blocks (for example best meeting window, handover time, deep work hours)
• Share plans as calendar events to keep everyone aligned
• Perfect for recurring meetings, standups, interviews, and cross border projects
WIDGETS: SEE TIME AT A GLANCE
Add DeltaClock widgets to your Home Screen for instant time zone visibility:
• City Time Widget: a stylish widget that shows the current time in your chosen city (great for your key teammate or client location)
• Project Timeline Widget: a compact view that highlights overlap windows across your project cities so you can spot meeting friendly hours quickly

HOW IT WORKS
1. Add the cities you care about (work, home, clients, travel).
2. Use the World Clock timeline to slide into the future or the past.
3. Switch to the Overlap Planner to find shared working hours.
4. Create a plan and export it as a calendar event to share with others.
BUILT FOR CLARITY
DeltaClock focuses on the most common multi time zone tasks: world clock comparison, time zone conversion, and meeting planning. Instead of doing math, you see the answer:
• “Is it too late to message London?”
• “When does Sydney start work?”
• “What’s the best meeting time for New York, Berlin, and Tokyo?”
• “If the deadline is 17:00 in LA, what time is that for me?”
USE IT AS A TIME ZONE CONVERTER
Need a quick time zone converter? Scrub to a time in one city and read the matching time in every other city. DeltaClock makes time zone conversion fast, visual, and reliable for daily scheduling.
