CoffeeWatch is a caffeine tracking app designed for people who love coffee and also care about how their body feels. For the first time, you can truly see your caffeine level in your body and your 24-hour metabolism curve—no more drinking by gut feel, no more pushing through on sleepless nights. Use data to protect your clarity, focus, and sleep. #Why We Built This App We’re a group of people who’ve survived countless late nights — powered by coffee. A “wake-me-up” cup in the morning, a “keep-me-going” cup in the afternoon, and a “let-me-finish-this-deck” delivery coffee at night. Some days it took five or six cups just to “look okay” in a meeting. But instead of feeling more stable, we ended up with: • Faster heartbeats, trembling hands, anxiety • Feeling more awake at night but sleeping lighter • And waking up even more tired — only to drink again It’s a loop: fatigue → more caffeine → worse sleep → more fatigue. We realized caffeine itself isn’t the enemy — The real problem is that we don’t know our current state. • How much caffeine is still in my body right now? • If I drink this cup, will I still be able to sleep tonight? • Am I already over my safe limit? So we made CoffeeWatch. --- # Features 1.

However, it is not reading my caffeine intake from Apple Health, even though I enabled that integration. Without this, the app is useless to me, as I am tracking my nutritions in a different app and just need this app to track and show my caffeine levels. **Developer response:** Hi, thank you for your feedback. We’ve taken your suggestion and fixed the Apple Health caffeine intake reading issue in the latest version, which is now available on the App Store. Please update to the newest version and make sure Apple Health permissions are enabled. If the issue continues, feel free to contact us through the app and we’ll be happy to help. ### 5/5 — 很好👌 *2026-01-05* 界面可爱又实用～(^з^)-☆ 17很丝滑～ 手表同时也又多一个功能呐～ ### 5/5 — Perfect App for Coffee Lovers *2025-12-23* Perfect caffeine tracking app!
