Very cool

I don’t understand a lot of the astronomy terms yet but this is a very unique way to visualize time. Very cool.

Response from developer

Thank you! We're glad you like it!

请求支持简体中文

Hello developer, I hope you can support Simplified Chinese. Many Chinese users do not know English or cannot understand it, which prevents them from using this app. They have to use translation software or AI to translate it, which is very inconvenient. Therefore, I hope you can add Simplified Chinese support to this app, as it would make it much more convenient for many Chinese users.

您好!非常感谢您的建议。我们正在为 Earth Clock(地球时钟)添加完整的简体中文支持——不仅是界面,还包括农历的月份与节气,以及每一种历法的介绍。完成后我们会在这里告诉您。 Hello, and thank you! We’re adding full Simplified Chinese to Earth Clock: the whole interface, the Chinese calendar’s months and solar terms, and every calendar’s description. We’ll update this reply when it ships. 我们非常乐意邀请您成为内测用户,欢迎点击此处加入。 We would be very pleased to have you as a beta tester, and we invite you join here: https://earthclock.app/testflight/

Super

Almost 5 star please include planet glossary so one can know the planets of each hour because size and color are rather vague and small . Love the app just what was looking for 👍🏽🌎☀️

Response from developer
