### 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.

### 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 😞

### 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.

### 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.

### 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 — 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.
