iPhone
Know your caffeine. The neon ring shows exactly where you stand — clean, dark, and distraction-free.
Koppio tracks your daily caffeine so you stay in control — not just aware.
The ring is the whole idea. One glance tells you how much you've had, how close you are to your limit, and whether you should skip that next cup. No clutter. No dashboardoverload. Just the number that matters.
TRACK WHAT YOU DRINK
Log any drink in seconds. Choose from common presets or enter a custom amount in mg. Every entry builds your history automatically.
SET YOUR OWN LIMIT
Health experts suggest staying under 400mg per day — but you set the rules. Pick a preset or dial in your own target. Koppio adapts to you.
SEE YOUR WEEK AT A GLANCE
The Stats view shows your daily averages, peak intake times, and projected caffeine clearance. Spot patterns. Make better calls.
SYNCS WITH APPLE HEALTH
Caffeine data is written to Apple Health automatically, so your records stay in one place alongside the rest of your health data.
BUILT FOR FOCUS
Pure black UI. Neon pink accents. No ads, no subscriptions, no account required. Just open the app and log your coffee.
