Track caffeine: scan barcodes, log sips, see active mg, personalized half-life, and your caffeine curfew for better sleep.
Stay on top of your caffeine intake with a simple log, clear visuals, and helpful timing estimates designed to support better daily planning.
Key features:
-Log drinks in seconds: Espresso, coffee, energy drinks, tea, soda, or custom entries
-Sipping duration support: Track slow drinks more realistically than “instant” intake
-Barcode scanning & search: Look up products via OpenFoodFacts and use estimated caffeine values when available
-Active caffeine estimate (mg): See an at-a-glance view of what may still be in your system over time
-Personalized half-life settings: Adjust your profile (age, weight, gender, and optional factors) to tailor estimates
-Sleep planning tools: Target a bedtime, view a projected “sleep-ready” time, and get a suggested caffeine curfew
-Trends & insights: Daily history plus a 7-day overview (totals, drink count, peaks, and bedtime estimates)
-Calibration: Optionally log how you feel to fine-tune the app’s internal estimate over time
-On-device storage: Your entries and profile are saved locally on your device
Important note:
All values are estimates based on common caffeine metabolism models and the information you provide. This app is not a medical device and is not intended to diagnose, treat, or prevent any condition.
