Stop Counting Calories.
Start Listening to Your Body.
The ancient Japanese wisdom of Hara Hachi Bu — eat until 80% full — is now a simple daily habit tracker. No more calorie math. Just mindful meals.
Calorie counting is
exhausting — and it's not working.
Numbers Over Feelings
Apps like MyFitnessPal force you to track every gram. You spend more time logging than actually enjoying your meal.
Calorie Counting Fatigue
Studies show that 97% of dieters regain the weight within 3 years. Restriction leads to bingeing. The cycle never ends.
Disconnected from Your Body
When you eat by numbers, you lose touch with your natural hunger and fullness signals. The result? Chronic overeating.

Hara Hachi Bu
"Eat until you are 80% full"
Rooted in Okinawan culture — one of the world's Blue Zones with the highest life expectancy — Hara Hachi Bu is a mindful eating philosophy practiced for centuries.
The stomach signals fullness about 20 minutes after you're actually full. By stopping at 80%, you honor your body's natural rhythm instead of fighting it.
No calorie charts. No macro goals. Just a simple check-in with yourself after every meal.
Three simple steps.
One powerful habit.
Log Your Fullness
After each meal, tap your fullness level — from Empty to Full. Choose your meal type and how you feel. No food database, no barcode scanning, no grams.
See Your Patterns
A weekly calendar shows every day at a glance. Tap any date to review that day's meals. Spot when you tend to overeat, and understand your triggers.
Track Your Progress
The Insights dashboard shows your Total Meals, current Streak, Mindful Rate, and average fullness. The 7-Day Trend chart highlights which meals were mindful vs. outside range.
Built-in Hara Hachi Bu Guide
New to the concept? The Guide tab explains the history of Hara Hachi Bu, why it works, and step-by-step tips for practicing it at every meal — right inside the app.
