What the iOS app adds
Six things only iPhone does well.
Apple Health, two-way
Steps and workouts feed your daily ring. Nutrition writes back to Health.
Lock-screen widgets
Today's ring on your lock screen. No app open.
Voice in your pocket
Hold the mic, talk, done. Works one-handed in the kitchen.
Coach with memory
Remembers your week, not just your meal.
Camera-first launch
Open the app, tap once, photo opens. No menu hunting.
Offline log capture
Photos save locally and sync when you are back online.
The AI calorie counter itself is the same model on web and iOS. The accuracy doesn't change.
When iOS is worth it
If you log on the go: yes. The kitchen-to-phone flow is faster than any web app on a laptop.
When web is enough
If you log at a desk: the web is enough. Same AI calorie counter, same accuracy, no install.
Most people end up using both. Web at the desk, iOS at the table.
