## What is caff.ai?

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.

### 3/5 — Can’t Delete Entries

*2023-12-02*

Not a bad app but has a limited database. You can add your own caffeine drinks however. 

Biggest issue is you can’t delete an entry once added. So if you make a mistake your are stuck. 😕

**Developer response:** Hey I'm glad you tried my app. I am working on making the drink selection more expansive. 

To delete an entry scroll down on the main dashboard to the drink in the 'Today's activity' section and tap on the entry. Tap 'delete' to delete the entry.

I am working on some UI improvements that will make deleting easier. Thank you for giving me feedback on my app.

### 1/5 — Useless

*2022-08-13, version 1.0.1*

There’s nothing useful about the app. Bad UI. Developer is spamming Reddit subs that have nothing to do with this content.
