Overlap: Time Zone Matrix

Finding the right meeting time across distributed global teams shouldn't require mental math or slow online converters. Overlap is a modern, high-performance time zone matrix built specifically for remote workers, distributed engineering teams, and global business travelers.

Key Highlights:

✨ The Golden Overlap Matrix
Instantly visualize where working hours intersect across multiple cities. The intelligent calculation engine dynamically highlights the "Golden Window"—the exact shared hours where all participants are awake and working simultaneously.

📊 Synchronized 24-Hour Timeline Grid
Scroll effortlessly across a unified 24-hour horizontal matrix. Pinned city headers, real-time UTC offsets, and a glowing live minute needle give you immediate clarity across every time track at once.

🎯 Interactive Work Hours Slider
Drag and resize your preferred business hours with tactile 30-minute snapping. Instantly see how changing your availability impacts your global overlap window in real-time.

⚡ 100% Offline & Instant
Zero remote API requests. Zero network lag. Overlap runs completely on-device using Android's native IANA timezone database. Full daylight saving time (DST) shifts and date rollovers (+1 day, -1 day) are computed dynamically with microsecond speed.

📱 Home Screen Widgets
Keep your distributed team's schedule at your fingertips with modern Material 3 widgets:
• Golden Window Summary: Live shared meeting window at a glance.
• Multi-Zone Matrix Clock: Real-time local clocks, UTC offsets, day rollover badges, and status pills (Work, Shoulder, Off-Hours) for all your primary tracks.

🔒 Private by Design
No accounts, no analytics, no ads, and no tracking. Your time zone preferences never leave your device.
