Common questions

How does Tabs estimate the caffeine in my system?

Each drink you log is absorbed over a short period, then wears off using a standard caffeine half-life of about five hours. The chart on the Today screen adds up every drink you've logged, so you can see your current level and where it's headed. Hold and drag on the chart to see the estimate at any time of day.

What is the sleep line?

The dashed line on the caffeine chart marks 50 mg. Where your curve crosses it is a rough guide to when caffeine is low enough that it's less likely to keep you awake.

How is my daily limit set?

Your limit is 5.7 mg of caffeine per kilogram of body weight, and never more than 400 mg a day. Tabs warns you as you get close. You can change your weight in Profile.

A drink is missing, or its caffeine amount looks wrong.

You can add any drink yourself as a custom drink. To get it added to the library for everyone, or to report a wrong amount, email us the brand, flavor, can size and the caffeine printed on the label. A photo of the label helps.

The barcode scanner isn't working.

• Make sure Tabs has camera access: Settings → Apps → Tabs → Camera.
• Hold the barcode flat and in good light.
• If a can isn't recognized, choose the drink from the list once. Tabs remembers that barcode for next time.

How do rankings and the global leaderboard work?

Rate any drink you've had out of 10 to build your own ranking. The Global tab shows each drink's average rating from everyone who has rated it. Your individual ratings and notes are never shown to other people.

Will my diary carry over to a new phone?

Yes. Your logs, ratings and settings are saved to your account. Install Tabs on the new phone and sign in with the same account.

I can't sign in.

• Check that you're connected to the internet.
• Update to the latest version of Tabs from the App Store and the latest version of iOS.
• Make sure you're signed in to the same Apple Account you used when you created your Tabs account, with iCloud Keychain turned on.
• Still stuck? Email us from the address on your account.

Something looks wrong or the app isn't loading.

1. Close Tabs completely and open it again.
2. Check for an update in the App Store.
3. Restart your iPhone.

Your diary is stored in your account, so deleting and reinstalling the app won't erase it. Just sign in again afterward.
