Caffeine Sleep Planner helps you log drinks and estimate when active caffeine may fall below your personal threshold. Quickly add common drinks, enter custom caffeine amounts, adjust half-life assumptions, and see a 24-hour decay chart. Home Screen and Lock Screen widgets keep your current estimate close by. Everything stays on device: no account, no server, no analytics, and no tracking. The optional tip jar uses Apple's StoreKit and does not unlock app functionality.
