### 4/5 — Too expensive

*2025-06-05, version 9.3*

This little app is simple and does what I was looking for but the price is too high for what it does.

### 5/5 — Great tool!

*2024-12-06, version 9.2*

Very helpful specially we are now global.

### 5/5 — Exactly the world calendar I want

*2024-10-11, version 9.2*

Thanks.

### 5/5 — World Clock

*2024-08-26, version 9.2*

Just downloaded the product. Working well. It helps to get the time in different cities so you can plan the calls in line with both parties working day. I like it. Colin Archer. Senior Consultant Wyse Corp.

Excellent concept!

### 4/5 — Liked the one time upgrade

*2024-02-23, version 9.1*

No ads for one payment (thought it might be yet another subscription)

Can create events/meetings on app to calendars!

### 5/5 — 超级方便！

*2023-03-11*

时差一目了然，太方便了！！！

### 5/5 — 免费简洁直观

*2022-12-08*

界面很简洁明了，可用于mac而且免费，非常棒！

### 5/5 — Clear and simple

*2020-12-25, version 8.0*

Very easy to use app. Clear and easy to view and understand

### 5/5 — 很方便

*2020-08-27*

超级方便 再也不用绞尽脑汁算时差了

### 5/5 — Great minimalist app

*2020-08-23, version 8.0*

Great easy to use minimalist app.

### 5/5 — Outstanding Visual time zone aid

*2019-08-26, version 8.0*

Showing it off to all my colleagues; being able to look across the red line across all the timezones at once - is FANTASTIC. Nothing really like it out there. Was hunting and found this for the iPhone and am back to get this for iPad. 5 stars and I use it ALL the time. Great App, great work.

### 3/5 — Cannot add new events with double tap

*2018-11-18*

双击没反应啊？是bug吗？怎么添加新events？

### 3/5 — Fantastic until recently

*2018-09-06, version 8.0*

Being able to display timezones by their abbreviations like EDT is incredibly useful. But this seems to have broken sometime in the past month and now only city names are displayed regardless of the abbreviation setting. It makes reading large timezone tables much harder if your geographic knowledge isn’t great.

### 5/5 — Great time tool

*2018-08-29, version 8.0*

I love this App. Simple to use and perfect for my meeting scheduling.

## Most critical reviews (10 lowest-rated)

### 1/5 — $20 for No Ads - wow!

*2025-10-31*

There are constant ads to buy the ad free version. Which is $20. That’s a lot for an app when I can bookmark dozens of websites that do the same thing for free. It’s a nice app but not worth $20 and the ads asking you to subscribe are annoying.

### 1/5 — Widget bug needs to be fixed

*2017-02-02, version 6.0*

The settings for size of widget expansion are not saved. XL turns back to medium without notice

### 1/5 — How to convert 15:00 ET ?

*2016-06-17, version 5.2*

Please advise how to convert 15:00 ET to HK time ?

Thanks

### 1/5 — Faulty

*2016-03-18, version 5.1*

Search feature doesn't work.  Crashes when you try to manually select a country to add.

### 1/5 — App crashes

*2015-10-30, version 5.0*

Sorry but it's true, it just crashes whenever u try to add a new zone

### 1/5 — Crashes when adding a city

*2015-02-02, version 4.3*

Looks great, but quit every time I tried to add a city.

### 2/5 — Crashes on iphone5

*2014-12-02, version 4.3*

Works on iPad, but crashes when adding a city on iPhone.

### 3/5 — Great app - nasty adverts!

*2025-12-20, version 11.2*

Love this app and have used for years! Unfortunately recently the advertising banner at the bottom on the free version has photos of penises, nude butts and lingerie!
I get the need to sell advertising to fund the free version but there should be some control over what customers see given the app is rated for 4+ age categories!
Nasty 😞

### 3/5 — All the others

*2021-02-15, version 8.0*

I had to rate Other apps bad because they don’t show Anthony/La Union, New Mexico. Please add those.

Add Ruidoso and other cities you’re forgetting.

### 3/5 — Missing big cities

*2019-01-26, version 8.0*

I need to know what time it is in Calgary, that is not an option despite it being a very large city in Canada. I have had to go with Edmonton instead.

### 5/5 — Simple to use

*2026-07-17, version 12.0*

Just a great simple little app. Easy to use particularly when working with people across multiple time zones!

### 5/5 — A Must Have for all Travelers

*2026-05-14, version 12.0*

Such an easy way to stay on track with meetings in various time zones

### 5/5 — A no frills efficient and well done App.

*2026-01-30, version 11.2*

This is a great little app. I work with and in multiple timezones and this app has saved me on multiple occasions. Spend the $20 and compensate a good developer.

### 5/5 — Im Großunternehmen bewährt

*2025-08-07, version 10.0*

Ich arbeite in einer großen IT-Firma mit Kollegen und Kunden aus vielen Ländern zusammen, und diese App hilft mir schon fast ein Jahrzehnt lang: Erstens sehe ich, wen ich jetzt sofort noch erreichen kann. Zweitens sehe ich, bis wann ich spätestens anrufen muss, um dem ausländischen Feierabend zuvorzukommen. Drittens kann ich für künftige Meetings Zeiträume finden, die für mehrere Zeitzonen passen. Viertens ist UTC einblendbar, um Missverständnisse bezüglich der diversen Sommerzeiten zu vermeiden.

### 5/5 — 看时区推荐！

*2025-05-16*

界面非常友好，直观且简介；最好的是可以增加很多个时区统一来看，很适合需要跨时区工作或者交流的朋友们！下载起来

### 5/5 — Very easy to use

*2025-03-22, version 9.3*

Clear display and can accommodate many cities

### 5/5 — Crossing many time zones

*2025-02-24, version 9.3*

I recently moved to Melbourne, Australia, but I continue to have a lot of business in Seattle, Dallas and Washington D.C.  World Calendar has made it so easy for me to know what time it is in those places any time I need the information.  This is a great app.  I highly recommend it.

### 5/5 — Great simple app

*2025-02-23, version 9.3*

Simple, easy to use app to see your calendar across time zones. Sync with calendars is okay but not 100% (canceled events still show up sometimes, can’t include video links on appointments made in calendar. But I use it everyday and it is strong on the fundamentals

### 5/5 — Great business tool

*2025-02-16, version 9.3*

We have three offices across three different continents. Coordinating meetings have always been difficult with other calendars. This calendar has saved me a lot of time and energy in dealing with time zone coordination.

I highly recommend the app. It’s wonderful.

### 5/5 — Great little app for international scheduling

*2025-01-21, version 9.2*

I needed to schedule a meeting with people in 4 different time zones in 3 different continents, and this little app came in extremely handy.  The $20 “remove ad” in-app purchase is exorbitant, but in the time I used it, the pop-up ads* weren’t obnoxious at all, thankfully.  Well worth a download if you need to schedule something internationally.

(I put that asterisk after “pop-up ads” because I only got pop-up “tool tips,” not actual ads lol)
