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.
