What is World Time Buddy?

How World Time Buddy functions as a visual converter

World Time Buddy describes itself as a convenient world clock, time zone converter, and online meeting scheduler. Its core web workflow is simple: add locations, mouse over hours to convert time at a glance, click hour tiles to schedule and share, and sign in to save settings.

Key components: world clock and scheduler

  • World clock – shows current time in multiple cities simultaneously
  • Meeting scheduler – suggests overlapping working hours across time zones

The implication: World Time Buddy turns a pain point into a two‑click operation. For distributed teams, that means less mental math and fewer scheduling errors.

TL;DR: World Time Buddy streamlines meeting scheduling for remote teams by eliminating manual time zone calculations.

How to download World Time Buddy on different platforms?

Download for Android from Google Play

The Android version is listed on Google Play with app ID com.helloka.worldtimebuddy and is published by HELLOKA LLC. It describes the app as a popular visual time converter, scheduler, and world clock.

Download for Windows desktop

While no dedicated Windows desktop app exists in the Microsoft Store, the web version works in any browser. The official site recommends using the web app for desktop access. Some users create a standalone shortcut using Chrome’s “Create shortcut” feature.

Install Chrome extension

The Chrome extension is available from the Chrome Web Store and provides one‑click access from the browser toolbar. A YouTube tutorial shows the process: visit the extension page, click “Add to Chrome,” and adjust saved settings.

Install iOS app from App Store

An iOS version is available on the App Store. The World Time Buddy mobile app page explains that it can be upgraded free of charge after a restore‑web‑purchase flow using dummy credentials (testing@example.com / testing123). Note: those credentials are provided for testing only.

The catch: platform reach is broad, but Windows and Linux users lack a native client – they rely on the web or a browser shortcut.

How to use World Time Buddy for scheduling meetings?

Setting up cities and time zones

On the web version, you can add or remove locations, set a home location, and reorder them. The interface uses drag‑and‑drop to rearrange cities.

Visual comparison of overlapping hours

Clicking and dragging across the time grid highlights the common working hours across all added zones. This lets you instantly see when both New York and Tokyo are awake.

Sharing meeting times with participants

Once you find a suitable slot, you can generate a shareable link that embeds the time in each participant’s time zone. That link can be sent via email or chat.

Why this matters: meeting scheduling is often a back‑and‑forth email chain. World Time Buddy eliminates that by showing everyone’s time in one shared view.

What are the key features of World Time Buddy?

Visual time converter

The visual converter shows hours side‑by‑side, allowing you to mouse over any time to see the corresponding time in other cities. This is more intuitive than a dropdown selector.

World clock display

The world clock shows current time in multiple cities simultaneously. You can add up to 200+ cities, though the exact limit is not documented.

Meeting planner

The meeting planner feature suggests the best times for a meeting across your selected time zones. It highlights overlapping business hours.

Browser extension and widget

The Chrome extension provides one‑click access. An Android widget is available for the home screen.

The trade‑off: feature‑rich for scheduling, but lacks historical data or sunrise/sunset times that competitors like Timeanddate.com offer.

How does World Time Buddy compare to other time zone converters?

World Time Buddy vs Timeanddate.com

Timeanddate.com provides broader data such as sunrise/sunset times, holidays, and a more detailed calendar. World Time Buddy, in contrast, is more focused on scheduling and uses a drag‑and‑drop interface that makes comparing multiple time zones faster.

World Time Buddy vs Every Time Zone

Every Time Zone uses a 24‑hour horizontal timeline and is simpler but less customisable. World Time Buddy allows you to pin cities and save sets.

Pros and cons

Upsides

  • Intuitive visual drag‑and‑drop interface
  • Free to use (no subscription required)
  • Cross‑platform: web, mobile, browser extension
  • Quick shareable links for meetings

Downsides

  • Lacks offline functionality – requires internet
  • No dedicated Windows or Linux native app
  • Less data (no sunrise/sunset, holidays) vs Timeanddate.com
  • Restore‑purchase flow on mobile is clunky (uses dummy credentials)

The pattern: World Time Buddy wins on speed and simplicity for scheduling. If you need encyclopaedic time‑related data, Timeanddate.com is the better choice.

The upshot

For remote teams juggling three or more time zones, World Time Buddy’s visual converter cuts scheduling time from minutes to seconds. The trade‑off is that you lose extra data like sun hours – but that’s rarely the point during a Monday stand‑up.

Step-by-step guide to using World Time Buddy

  1. Access the web version – Go to worldtimebuddy.com in any browser. The interface loads instantly with New York and London as defaults.
  2. Add cities – Click “+ Add Location” and search for your target cities. You can add up to a dozen without performance lag.
  3. Compare times visually – Mouse over the hour tiles to see the time in all added cities update in real time. You can click a tile to select a time and then share it.
  4. Schedule a meeting – Drag to highlight a block of time. The top bar shows which cities are within business hours for that block.
  5. Share the link – Click the share icon (or right‑click the selected time) to copy a link. You can send this to colleagues, and it will open World Time Buddy pre‑loaded with the selected time in each person’s local zone.
  6. Install the mobile app (optional) – Download from Google Play or the iOS App Store. The mobile app mirrors the web functionality with touch‑optimised controls.

The step-by-step process makes it easy for even first-time users to get started quickly.

What to watch

The mobile upgrade flow requires dummy credentials for restoring a web purchase – a sign that the purchase system is still a work‑in‑progress. If you buy on the web, expect a slight friction when moving to mobile.

Clarity check: what we know and what we don’t

Confirmed facts

  • World Time Buddy provides a web version and mobile apps for Android and iOS
  • Has a browser extension for Chrome
  • Used by millions of people worldwide
  • Free to use with optional paid upgrade

What’s unclear

  • Future roadmap – no official statement on upcoming features
  • Exact number of supported cities (estimated 1000+ but not confirmed)
  • Offline functionality – no support documented
  • Cross-device sync reliability – limited based on user reports

The pattern: the product has strong core functionality and broad adoption, but the lack of a public roadmap and limited offline capability leave some power users wanting more.

Quotes from users and reviewers

I’ve been using World Time Buddy for years. It allows for a calendar view and shows multiple cities together.

— Hacker News user in a product discussion

World Time Buddy offers several options: a browser tool, a mobile app, and a widget.

— Teamup blog, a productivity publication

These quotes reflect user satisfaction and the tool’s reputation for reliability and ease of use.

Final takeaway for distributed teams

World Time Buddy delivers exactly what it promises: a fast, visual time zone converter that makes meeting scheduling painless. For remote teams working across three or more time zones, the choice is clear: use World Time Buddy for your daily stand‑ups and quick calls, or switch to Timeanddate.com when you need sunrise times for a global event. But for the 90% of use cases that just need to know “is it a good time to call?” – World Time Buddy is the tool that will save you five minutes a day, every day.
