What's New in Caffeine Sleep Planner

1.4

August 13, 2026

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.

Great Idea!

Since this app is in its infancy stages, it starts with a great concept. It would be nice to be able to edit logged data and the timeline at the bottom of the graph is illegible, it should be readable and or free flowing when the user moves the cursor back-and-forth. I will purchase this app, hoping that the developer will make improvements upon this app as I have not seen another one like it yet.
