Native Windows integration

Astral features Windows integrations such as detailed app notifications, lock screen info, and a popup taskbar agenda calendar like Windows 10 used to have.Also because our app is built for Windows, you get the speed and style that comes with a dedicated app experience.

Function comes first

Not just a pretty face - we believe that having an intuitive and quick interface allows you to work faster and easier. All of our controls are built around getting you information with the least fuss.Digging through layers and layers of menus and waiting for flashy animations doesn't happen here.

Design still shines through.

Created with the latest Windows design guidelines in mind, you'll never get tired of looking at your calendar again.Choose between Mica, Acrylic, and other color themes to match your taste.Functional doesn't mean ugly.

Frequently Asked Questions

  • Is Astral free?
    Astral will always have a well featured free tier for non-commerical use. Free users will be able to use most functionality that does not require an Astral account, and are limited to two Google Accounts.

  • Is my calendar info safe?
    Yes, all of your calendar info stays on your computer - it is never transferred to our servers, and neither is the token that allows Astral to talk to Google. We do not have any analytics built into Astral - the only info that we have access to are crash reports, which do not contain any links to account information.

    Also the app has been certified by both the Microsoft Store, and passed a manual review required by Google for calendar access.

  • Why make this app?
    Like many others, I used the Mail and Calendar Windows apps, and was dissatisfied with the replacement Outlook web app. I wanted better integration with Google Calendar, while still maintaining Windows integration.

  • Will you ever support other calendars?
    Yes it is possible, although not currently planned. Likely outlook/Microsoft accounts would be next, as they also have a relatively open API. Eventually it would be nice to add CalDAV support, which would bring with it iCloud support and others.

  • How do you make money?
    The plan is to have a paid tier for commercial and power users. This would have unlimited calendar account support, as well as niceities such as autocomplete when writing addresses/locations, weather service integration, etc (services which themselves require money for usage).

  • Will the paid tier be a subscription?
    Yes this would likely be a subscription. Unfortunately the way development is structured, having a steady source of income allows for continued development, which requires a subscription. Likely it will be a nominal amount, something like ~$5 a month / $50 a year. Our hope is that many people will be fine with just the free tier, and those who wish to support Astral can do so via the subscription.
