Caffeine Clock

✨Key Features

• ▸Brand-Specific Calculator: Choose from major US coffee chains (Starbucks, Dunkin', Peet's Coffee, Tim Hortons, McDonald's McCafe, Dutch Bros, Caribou Coffee, Panera Bread, The Coffee Bean & Tea Leaf) with pre-set caffeine amounts for accurate estimates.
• ▸Simple Input Process: Select your coffee brand, enter the exact hour and minute of consumption, then click "Calculate" to see metabolism results.
• ▸Focus on Sleep Optimization: Shows when caffeine levels drop low enough to avoid disrupting sleep, helping users decide the ideal cutoff time for their last caffeinated drink.
• ▸Metabolism Tracking: Provides insights into how caffeine is processed in the body based on timing and amount, promoting healthier habits.
• ▸Web-Based & Straightforward: Minimalist interface with no sign-up required; quick and easy for on-the-go checks.
• ▸Related Ecosystem Note: The developer behind Caffeine Clock also offers a full mobile app version (caffeineclock.app) with advanced tracking (200+ items, graphs, analytics, custom entries, offline use), but the .com site is a focused web calculator primarily for coffee brand metabolism timing.
