Caffeine Tracker Who's Cracked

Who's Cracked is a caffeine tracker for a group chat.

Scan the barcode on a can and it fills in the size and the caffeine for you. Your friends see it. The leaderboard updates. That's the whole loop, and it takes about five seconds.

WHAT IT DOES

• Scan any can, bottle or cup. The catalog knows most of them, and you can fill in the rest straight off the label.
• See what your friends cracked, where they were, and what they thought of it.
• A leaderboard for today, the week, the month, the year, or all time.
• Heart and comment on anyone's crack.
• A map of everywhere you have cracked one.
• Home screen and lock screen widgets: today's count, your caffeine, your week, and who cracked last.
• The Damage Report: your year in caffeine, as cards you can share.
• Optional: connect Apple Health and each crack shows what your heart rate did in the hour after. Read-only, off by default.

IT WORKS ALONE TOO

No friends on it yet? It is still a caffeine log that fills itself in from a barcode. Your day, your week, your worst habits, all counted for you. Add people whenever you want and the whole thing turns into a leaderboard nobody asked for.

HONEST ABOUT YOUR DATA

• Location is optional on every single log, foreground only, and skippable with one tap.
• Your logs are visible to the friends you accept, and you can mark any of them private.
• No ads, no trackers, nothing sold to anyone.
• Delete your account, and everything with it, from inside the app.

Caffeine figures come from product labels and community input, so they can be wrong. This is not a health app and it gives no medical advice. Know your own limits.
