Understand your skin — one day at a time. Trigger is a personal skincare tracker that helps you spot the patterns between your daily habits and how your skin looks. Instead of guessing what's behind a breakout, log what you do and let Trigger surface the possible connections over time. HOW IT WORKS • Log daily in under a minute — skin status, food, shaving, stress, sleep, and more. • Add weekly photos and get an AI skin-score estimate to track visible change over time. • See possible triggers ranked by how often they line up with your breakouts. • Build a barrier-first routine and check product ingredients as you go. WHAT YOU CAN TRACK • Daily skin status and barrier symptoms • Food, supplements, shaving, sleep, stress, and workouts • Weekly photos with per-zone AI estimates • Your skincare routine, with ingredient flagging • Local weather (humidity, UV) as an environmental factor BUILT AROUND YOUR PRIVACY • Your logs and photos are private to your account. • No ads. No third-party analytics or tracking. • Export all of your data or delete your account anytime. A CLEARER PICTURE Trigger uses AI to estimate skin scores and surface correlations from your own logs — giving you a clearer picture to bring to your own routine or your dermatologist. Trigger is a tracking and educational tool. It does not provide medical advice or diagnosis. Always consult a qualified dermatologist for medical concerns. Trigger offers an optional auto-renewing subscription, Trigger Pro: • Monthly — $6.99 (with a 7-day free trial) • Annual — $49.99 Trigger Pro unlocks AI trigger analysis, AI photo scoring, weekly AI briefings, derm-ready PDF reports, and guided elimination tests. Payment is charged to your Apple ID. Subscriptions auto-renew unless canceled at least 24 hours before the end of the period; manage or cancel anytime in your Apple ID settings.
