Slather reminds you when to reapply sunscreen — so you stay protected without watching the clock. It checks the live UV index for your exact location, you pick your SPF, and Slather counts down to your next reapplication, sending a reminder the moment it's time. • Live UV index for your location (via Apple WeatherKit) • Pick SPF 15 / 30 / 50 / 50+ — the reapply window adjusts to match • A clear countdown with a reminder when it's time to reapply • Live Activity on your Lock Screen and Dynamic Island • Apple Watch app + complications — glance at the UV and reapply, or start a session, from your wrist • UV-exposure history, with optional sync to Apple Health • Light and dark mode Slather asks for Location (to look up your UV) and Notifications (for reminders). There's no account, no ads, and no tracking — your data stays on your device. Heads up: the UV index reads 0 (Low) at night or indoors — that's correct, not a bug. Step outside in daylight to see a real reading. Slather Premium (optional) Everything above is free — live UV, SPF timing, reapply reminders, the Live Activity, the Apple Watch app, and Apple Health sync. Premium adds two extras: • Family profiles — track SPF and reapply timers for everyone you protect • Weekly insights — your sessions, protection time, and strongest sun days • Slather Premium — $4.99 per year, starting with a 7-day free trial • Slather Premium Lifetime — $14.99, a one-time purchase Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless it is canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the end of that period.
