Empower yourself to make smarter choices for more restful nights and productive days.
- Effortless & Detailed Logging: Quickly record your caffeine consumption with a user-friendly interface. After logging, you're brought back to the "Today" screen for an immediate overview. Customize your beverage list with:
- Smart Sorting Options: Sort your drink list by "Last Used" or "Most Used" for even faster logging.
- Intelligent Sleep Prediction: See a real-time estimate of when your caffeine levels will be low enough for quality sleep based on your intake and personalized settings.
- "What-If" Scenarios: Instantly preview how an additional drink might affect your predicted sleep time before you consume it, right from the drink selection list.
- NEW! Personal Metabolism Assistant: Answer a series of guided questions about your caffeine experiences. The assistant then analyzes your responses to suggest personalized values for your sensitivity, half-life, thresholds, and decay delay, helping you fine-tune the app for maximum accuracy.
- Personalized Metabolism: Tailor caffeine decay calculations precisely to your body with adjustable:
- Caffeine Sensitivity (Low, Medium, High).
- Sleep Readiness Threshold (the caffeine level where you feel ready for sleep).
- Edgy Threshold (the level where you might start feeling jittery).
- Caffeine Half-Life (how quickly your body processes caffeine).
- Delay Before Decay (accounts for absorption time).
- Multiple Decay Models (e.g., Standard Half-Life, Linear).
- Maximum Daily Intake limit.
- Sleep Correlation Insights: Analyze how different daily caffeine amounts correlate with your sleep duration imported from Apple Health. You can now also customize the caffeine amount thresholds that define "Little," "Some," "Plenty," etc., in this view for more meaningful personal insights.
- Smart Daily Log Reminder (Optional): Receive a gentle nudge only on days you haven't logged any caffeine yet.
- HealthKit Integration:
- Write caffeine consumption and drink volume (as water) automatically to Apple Health.
- Read sleep analysis data for deeper correlations and insights.
