Sundial+ App Store

Introducing Sundial+

Sundial+ main screen on iPhone

Welcome, Sundial Fan

Sundial+ is the next generation of the Sundial app for iPhone, iPad, and Apple Watch ("Sundial Classic"). Sundial+ is two years in the making, a 100% rewrite of the original app using Apple's latest tech: Swift and SwiftUI.

Sundial+ has dozens of new features including support for golden and blue hour, configurable app home screens, support for 28 languages, and more customizable alerts with alarms and custom sounds. Most Apple Watch complications and widgets are now configurable, giving users even more options.

Sundial+ is a new app in the App Store. Sundial Classic will remain available to existing customers: your purchase is still valid, and you can continue using it and reinstalling it on compatible devices from your App Store purchase history. Please see my Sundial Classic FAQ for more details and assistance.

Basic Sundial+ features are free on iPhone and iPad, while alerts, widgets, Apple Watch complications, and advanced features will require a subscription. Your subscription helps fund maintenance and the development of new features.

Sundial+ requires iOS 26 or later, iPadOS 26 or later, and watchOS 26 or later.

What's New in Sundial+

Sundial+ has a whole bunch of new features:

  • General improvements
    • Sundial+ Magic Hour screen on Apple Watch
      Golden hour and blue hour (aka "magic hour") are fully supported: show them on the dials, create alerts for them, and include them in widgets and complications. You can adjust the sun angle that defines these periods in the Sundial+ Settings screen.
    • Improved accuracy of all solar and lunar data. Sundial Classic used simpler formulas to work within the limited CPU resources of early Apple Watches and iPhones, especially for background complication and widget updates. With older models phased out, I can now use more complex models.
    • Adopts Apple's Liquid Glass design language.
    • Available in 28 languages.
  • Alert improvements
    • Sundial+ wake-up alarm on iPhone with snooze and stop controls
      Turn an event alert into an alarm: wake up before sunrise, dawn, or another solar or lunar event. Alarms ring even when your iPhone is in Silent mode or a Focus mode is active, with an optional snooze when you need a few more minutes.
    • Personalize each alert with a custom sound, image, or emoji.
    • New alerts for golden hour and blue hour.
    • New alerts for waxing crescent, waxing gibbous, waning gibbous, and waning crescent moon phases.
    • New alerts for Spring and Fall equilux, the days near each equinox when day and night are closest to equal in length at your location.
    • Adding new alerts is even easier: you can now search for events and sounds.
    • You can export a preview of your upcoming alerts as a PDF, HTML, or Markdown file for a handy reference. Find this in the Alert Settings screen.
    • Improved formatting for alerts and notifications on iPhone, iPad, and Apple Watch.
    • Long-press a notification on iPhone or iPad to get a list of recent and upcoming notifications.
  • iPhone and iPad App improvements
    • Configurable home screens: select which solar and lunar data to show, and switch between different home screen sets.
    • The time sweep on the dial now indicates the current time more precisely.
    • Time travel can now jump to a specific time in addition to a specific date.
    • Sundial+ on iPad now supports portrait mode, multitasking, and windowing.
  • Apple Watch widgets and complications are now fully configurable, just like their iPhone and iPad counterparts.
  • Comprehensive iPhone Duo support.

Special Offers for Sundial Classic Customers

If you purchased Sundial premium extras within the last year, you can claim a free one-year Sundial+ subscription. If you purchased a Sundial extra more than a year ago, you can claim a free three-month subscription.

If you accept the offer, the subscription will not renew automatically: the free period simply ends after twelve or three months unless you choose to subscribe later. So there is no catch.

The offer will appear when you launch the latest version of Sundial Classic available in the App Store (Sundial v10.17 or later). If you have already seen it, you can display it again in Sundial's app settings. The offer can be redeemed only once.

Your Sundial Classic settings, widgets, and complications will not automatically transfer to Sundial+. But there is a special one-time alert configuration import. First, launch Sundial Classic v10.17 or later. Then, the next time you launch Sundial+, it will prompt you to import your Sundial Classic alert definitions.
