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 THREE BEAUTIFUL THEMES Choose the look that fits your style: • System / Liquid Glass • Neumorphic • Retro Neumorphic A clean interface makes time zone conversion and scheduling feel effortless. WHO IT’S FOR DeltaClock is made for: • Remote work and global teams • Managers coordinating schedules across time zones • Freelancers with international clients • Students attending classes in another country • Travelers planning itineraries and check ins • Long distance relationships and families WHY DELTACLOCK DeltaClock combines a world clock, time zone converter, widgets, and meeting planner in one focused app: • Fast setup: add cities, compare time zones, find overlap • Visual timeline: understand time differences at a glance • Fewer mistakes: avoid missed meetings caused by DST or date changes • Calendar sharing: turn overlaps into real plans • Widgets: your key cities and project overlaps always visible Work across time zones with confidence. Compare time zones, plan meetings, and set time zone reminders with DeltaClock. 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.

You have goals. You have things you want to accomplish. But sometimes, staying focused long enough to actually do them is the hardest part. Rush Hour helps you take back control of your time. Start a focus timer, record your work session in timelapse, block distracting apps, and reflect on how you actually spend your time. FOCUS WITH A TIMER Set a timer and commit to the task in front of you. Whether you're studying, working, creating, or simply trying to get something done, give yourself a dedicated space to focus. RECORD YOUR WORK Turn on timelapse while your focus timer runs. See your work session from start to finish and make your effort visible—not just the final result. BLOCK DISTRACTIONS We all have those apps we open without even thinking. Block distracting apps during your focus session to make it easier to stay away from the things that pull you off track. REFLECT AFTER EVERY SESSION When your session ends, take a moment to look back. How many times did you get distracted? How did the session go? Did you show up for the work you wanted to do? TRACK YOUR PROGRESS Build a clearer picture of how you spend your time and how consistently you show up. Use your sessions as a reminder that progress comes from small efforts repeated over time. Progress doesn't have to be perfect. It just has to keep moving. Start your next session. Show up for yourself.
