CrashGuard

CrashGuard is a mobile app (iOS/Android) with optional web dashboard that helps people use energy and functional drinks without wrecking their sleep, anxiety, or focus. You log what you drank (brand, size, time) by barcode scan or quick search, plus optional factors like body weight, bedtime, workouts, and meds. The app estimates caffeine timing, likely crash window, and sleep impact, then suggests safer alternatives (lower caffeine, L-theanine blends, hydration/electrolytes) and timing adjustments. It also tracks tolerance creep over weeks and flags when your “normal” intake is trending into risky territory. This is an AI + traditional app: AI helps with brand matching, ingredient parsing, and personalized recommendations, while core calculations remain transparent and user-controllable. It’s not a miracle health app—just a practical decision tool for daily use.
