On iPhone and iPad
- Discover the new Liquid Glass design: UI elements feel gently illuminated, carrying a subtle echo of sunlight.
- New Peek Panel: A lightweight element that quietly shows simple info like "Moon above horizon." It fluidly expands to reveal more detail, such as "Sets in 20 min" when you need it, fading back automatically. Designed to balance presence and absence, it keeps information accessible without overwhelming the interface.

- Make the Quick Access Menu your own by reordering modes... the first three are always at your fingertips.
- The new Season widget now lets you choose between astronomical or meteorological seasons.
- Updated widgets and app icons now match the new home screen's tinted and clear styles.
- And many thoughtful refinements across the app.
Foundation Model Features (iOS 26 + iPadOS 26)
- Mode-Specific Weather Insights: Smarter, activity-aware tips.
- State of Mind Suggestions: Personalized, context-aware guidance that adapts to your state of mind log.
- Astronomical Events: Tailored explanations that transform solar events into relevant insights for Photography, Hiking, Mindfulness, or Travel.
- Review System: A simple thumbs up/down or alternative request helps refine future insights, while keeping all data private on your device.
On Apple Watch
- Experience the new Liquid Glass design on your wrist.
- Quickly enable or disable sun event notifications right from Control Center.
- Add a configurable Season complication for astronomical or meteorological seasons.
- Added support for the latest iPhone 17 Series, iPhone Air, Apple Watch Series 11, Apple Watch Ultra 3, and Apple Watch SE 3.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
