## What is Duskly?

HOW MUCH CAFFEINE IS STILL IN YOUR BODY?

You had coffee at 2pm.
It's 8pm now.
Half of it is still in your system.

That's why you can't sleep.

Most people consume 300mg+ of caffeine per day without realizing it. Coffee, tea, cola, chocolate, even decaf... it all adds up.

Duskly shows you the truth.

SMART CAFFEINE TRACKING
No generic rules. Duskly calculates your real caffeine half-life and tells you exactly when you'll be sleep-ready. Track coffee, tea, energy drinks, soda, chocolate, everything.

SLEEP READINESS SCORE
One number. Five factors. Checked before bed, not after. Other apps tell you tomorrow that you slept badly. Duskly tells you tonight what to change.

YOUR CAFFEINE CUTOFF
Duskly warns you when it's too late for caffeine and suggests lower-caffeine alternatives.
