Photo in, estimate out
Use the camera or photo library to capture food or drink. When you run an analysis, CalScai uses an encrypted internet connection so automated image understanding can return structured nutrition style estimates. This is not medical advice, but a practical same day signal.
Today
Ring, macros, hydration
The Today tab rolls up calories against your goal, shows protein, carbs, fat, and logged hydration, and keeps a swipeable meal list for the day you select on the calendar.
Settings
Fine tune without leaving the app
Adjust your calorie goal, add manual calories for meals you did not photograph, and log plain water so the hydration bar matches how you actually drank.
