Water Tracker CoffeeWatch vs Revna

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.
