Free · In‑App Purchases · Designed for iPad. Not verified for macOS. I want to start by praising you for creating a beautifully designed app. The UI is genuinely pleasant to look at, and the UX is straightforward, intuitive, and easy to navigate. Everything feels thoughtfully laid out, which makes the app enjoyable to use.I will be upfront in saying that I do not fully understand the physiology behind how the human body metabolizes caffeine, including factors like timing, dosage, sex, weight, height, and other variables. I am hoping that you do, and the app certainly gives that impression. However, as a user, I currently have no way to understand or verify how these calculations are being…from apps.apple.com

Caffeine Clock – A beautiful and accurate caffeine tracker app2025 · caffeineclock.app · ▲14Hi guys! I would love to show you Caffeine Clock 2.0, a tracker I made that shows you your caffeine levels now and in the future, helping you have undisrupted sleep by timing your caffeine better.
