caff.ai helps you manage caffeine with clarity: Get reliable energy during the day without wrecking tonight's sleep
Still lying awake because of that afternoon coffee?
caff.ai helps you understand exactly how much caffeine is active in your body right now, how much will still be active at bedtime, and when to stop so you can protect your sleep.
Just log what you drink and caff.ai shows you:
• your active caffeine level right now
• your projected caffeine level at bedtime
• your last call for caffeine
• when your caffeine will drop low enough for sleep
• your daily and weekly caffeine patterns over time
Whether you're trying to sleep better, avoid jitters, reduce caffeine headaches, or stay sharp without overdoing it, caff.ai helps you make smarter caffeine decisions throughout the day.
Key features:
• active caffeine tracking based on a research-backed caffeine model
• bedtime projections and a personalized bedtime caffeine target
• last call timing so you know when one more drink will still fit
• home screen widgets for at-a-glance caffeine guidance
• custom drinks and adjustable serving sizes
• customizable daytime target range
• smart reminders and last call notifications
• Apple Health export support
• weekly history so you can spot patterns and improve your routine
With caff.ai on your home screen, your caffeine plan stays visible without needing to open the app.
Stop guessing. Stop haphazardly caffeinating.
Use caff.ai to time caffeine better, protect your sleep, and feel more consistent, energized, and in control every day.
