One line, four stages.
The energy line fills as you eat. Its colour changes with the stage you're in, and what's ahead stays faint. Scroll through a day.
Morning · lose weight
1,180 kcal to your goal zone
Start the day with room to eat. The line is empty, and everything ahead is faint.
Afternoon · lose weight
350 kcal to your goal zone
Each meal you log fills the line. The number tells you how far you are from your goal zone.
Evening · in the goal zone
180 kcal of room left in your goal zone
Inside the zone the line turns green. You can see exactly how much room is left.
Late · smaller deficit
+240 kcal past your goal zone
Go past it and the line warms to amber. No red, no guilt. Just a smaller deficit today.

Questions
Is BAVIII medical advice?
No. It offers general guidance on food, training and recovery from the information you choose to share. Talk to a health professional before big changes.
Do I need an Apple Watch?
No. Your iPhone counts steps on its own. A Watch adds sleep, heart rate and HRV, which makes readiness more useful.
What happens without a signal?
Food, meal prep and workouts save on your iPhone and sync when you're back online. Recent screens stay readable.
Is there an Android version?
Not yet. BAVIII is launching on iPhone first.
