#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.

It’s here to help you understand whether your body can still handle it.
Because staying awake shouldn’t come at the cost of losing sleep.
