Eat from the container. We'll do the math.

Massed is a mobile app that reads your kitchen scale and logs what you ate from a before-and-after photo.

Full container on scale — Start full 1250 g

Pour into bowl — Add what you want

Weigh what is left — Snap what is left 450 g

Before and after, without the mental math

Weigh the container full. Use what you need. Weigh it again. Massed logs what left.

Before & After

Eating from the jar, bottle, or tub? Weigh the container before you scoop, then again when you're done. Massed subtracts and saves what you used.

Single item

Weighing one ingredient, not a container? Put it on the scale, snap a photo, and Massed saves the weight.

Quit guessing how much you actually ate.

A before photo and after photo are all it takes. Massed reads both weights and saves the amount you used.
