What's New in Helios UV
1.1.1
October 1, 2026
• Siri, Spotlight, and Shortcuts: ask for the current UV, how long until you burn, or when UV drops below your target, and switch between your saved locations. Works from the Action button too. • Apple Watch on watchOS 27: complications pick up a fresh forecast from your iPhone right away, ease into forecast revisions instead of jumping, and the UV Gauge shows its "UV" caption again. • Home Screen widgets in the Tinted and Clear styles keep a clear hierarchy: the UV number, category, and gauge take the accent while the rest stays quiet. • Picking a Pro target UV on the Free tier now opens the Pro screen, the way picking a Pro color scheme does. • Forecast times line up everywhere: the target time, the widget flip, and the notification share one crossing, and "All UV times" says "Tomorrow" for levels reached the next morning. Half-hour time zones are exact. • Turning notifications back on alerts you right away if UV is already above your target, and scheduled alerts survive a time zone change. • Billing problems show up: a subscription in payment retry gets an "update payment" prompt instead of quietly reading as Free. • "Change Sun Profile" returns straight to the dashboard, background refresh re-arms when you leave the app, and onboarding scales with your text size. • VoiceOver: location search announces what happened, the trend is spoken in widgets and complications, and secondary text is easier to read. • Offline, the paywall and Restore Purchases say "No internet connection." in all 10 languages, plus translation fixes across the paywall and the watch.
