Frequently asked questions

Is Brewnap medical advice? No. Brewnap’s numbers are estimates based on a simple decay model and published research averages. Individual caffeine sensitivity varies a lot. Don’t use Brewnap as medical advice — see the References section in Settings for the sources behind the estimates.

Why did my caffeine level reset / look wrong? Brewnap calculates your level from the drinks you’ve logged and your settings (bedtime, sleep-ready line, caffeine clearance speed). Check Settings to make sure your clearance speed matches how you typically feel, and check History to confirm your recent entries are correct — you can edit or delete any entry there.

How do I change the default drinks? Settings → Manage drinks. You can edit the built-in drinks or add your own (up to 6 total on the free plan, unlimited with Brewnap Pro).

What does Brewnap Pro include? Week and month history trends, Apple Health sync, unlimited custom drinks, and Apple Watch support. See Settings → Brewnap Pro for current pricing.

How do I restore my purchase on a new device? Settings → Brewnap Pro → See plans → Restore Purchases.

Does Brewnap work without an internet connection? Yes. Brewnap stores everything on your device and doesn’t need a connection for its core features. A connection is only used for App Store purchases.

Does Brewnap send my data anywhere? No — see our Privacy Policy for details.
