Your protein ring, front and center
The protein ring shows exactly where you stand — with calories, carbs, and fat alongside.
Always visible, without opening the app
Lock- and home-screen widgets show your progress and reset at midnight. The Live Activity brings your rings into the Dynamic Island.
Goals that fit you
Grammo calculates your calorie and protein goal from your details (Mifflin-St Jeor). All values are estimates, not medical advice.
Reminders only when you need them
Smart reminders show up only when they're useful — no constant nagging.

Widgets & Live Activity
