About this app

Start with a visually stunning virtual Earth in the palm of your hand: Real satellite photos drive a live simulation of day/night, clouds, seasons, sun, moon and more. Then, our unique clock and compass track the local movements and transitions of the sun and moon. It’s everything you need to stay connected to the world you live in.

And not just your local time: create a list of locations to show on the globe, and now this beauty is a world clock, too. See it all at a glance: not just what time it is in other places, but how those times relate to each other. It's the nature of time.

Lots of extras complete the picture: alarms, augmented reality, home screen widgets, live wallpapers, Wear OS watch faces. There’s no other app like TerraTime.


Great for travelers, astronomers, weather watchers, geographers, teachers, photographers, fishermen and other outdoor types - as well as just about any geek you can think of.

Superbly stylish, incredibly detailed and unbeatably useful - LifeOfAndroid.com

Beautiful design. I really appreciate a date/time app that displays so much information on such a clean interface. Three features I'd love to see: a soft button that links to my phone's native alarm function, an "always on" option - at least for when the phone is on a charger - and a native swipe up/down (or similar) function to adjust screen brightness. These features would make this an excellent desk clock. UPDATE: The more I use this app, the more I like it! Yet I'd still like to see other optional functions: my work is logged in GMT, so it would be nice to have a small GMT display. I'd also like to see an option to display a seconds hand, both sweeping (like a mechanical watch) and ticking (like a quartz watch), and a soft button to re-sync the phone's internal clock to a time server or, better, to GPS. I'm a mechanical watch enthusiast, and these last functions would allow me to use TerraTime Pro, exclusively (rather than separate time hack apps).

This is a good, user friendly app. for world times. An improvement would be if it also gave the temperatures in the same cities. It would also be useful if a person could sign into their email address, in the app. This would make it possible to transfer cities saved, from an old phone, to a new phone.

Working perfectly with stunning visuals, and then some! I was dreaming of a real-time world map showing day/night changes as my live wallpaper—and this app not only exists but exceeds all my expectations. (I did not even dream of live clouds & polar ice coverage.) *My constructive criticism*: (1) The globe mode could add a fixed earth natural axis rotation mode—users can rotate the earth around 23.4 degree of obliquity. (2) The settings menu seems a bit complex. (3) I don't really understand how to read the moon's arc on the clock, even after checking out your website. Perhaps some more explanation could be added? 🤔

Thank you! The globe can be set to Ecliptic orientation (it's in the "complex" Settings area) - is this what you want? Also, the moon arc is in the Layers dropdown on the main screen, rather than in settings.

What’s new

• Improve tab navigation
• Fix bug: alarms can't be set for x:00
• Several other bug fixes
