Caffeine Sleep Planner

Caffeine timing for sleep

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

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.

This update focuses on making it easier to build a caffeine and sleep routine you can stick with: - Streaks: see how many days in a row you've stayed under your bedtime caffeine target, right on the Today tab. - A friendlier first launch that walks through Quick Log, the Daily Companion, and the Decision Simulator. - New optional reminders: a gentle daily check-in, a streak-at-risk nudge, and a weekly insights-ready alert. All off by default — turn on only what's useful to you in Settings. - Small polish throughout Settings, including a direct link to rate the app. As always, everything stays on your device: no account, no server, no tracking.
