RayLimit: Sun Exposure Timer
UV Tracker & Vitamin D Timer
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Whether you want a natural golden tan, need to hit your daily vitamin D goals, or just want to get outside safely — RayLimit tells you exactly how long to stay in the sun, based on science.
KEY FEATURES:
SMART SUN TIMER
Start a session and RayLimit counts down your safe exposure window in real time. Get notified before you burn — not after.
SUNSCREEN SCANNER
Scan your sunscreen or tanning oil to instantly analyze its ingredients. RayLimit highlights potential risks, flags harmful or controversial components, and helps you make safer choices for your skin.
PERSONALIZED TO YOUR SKIN
Input your skin type, existing tan level, and current UV index. RayLimit calculates your personal burn time and vitamin D production — no guesswork.
UV INDEX MONITORING
See real-time UV conditions for your location. Know exactly when the sun is strong enough to matter — and when it's time to seek shade.
VITAMIN D TRACKER
Track daily vitamin D from sun sessions and supplements. See your running total and know when you've hit your healthy daily target.
TANNING ROUTINES
Pick from built-in routines like “Quick Flip” or “Shade Break,” or create your own step‑by‑step routine. Get timed cues for flips, sides, and breaks so your tan develops evenly and safely.
SMART REMINDERS
Get alerts to flip, reapply sunscreen, or wrap up your session — all timed to your session, not just a generic clock.
SESSION HISTORY
Review past sun sessions, track your tanning progress, and build smarter habits over time.
