01 / THE CONTEXT

A reason
to build.

Health Journal makes nutrition tracking effortless. Instead of searching databases and measuring portions, just type what you ate — 'I eat a bagel and 2 tablespoons of honey' — and AI estimates calories, protein, carbs, and fat.

See your daily nutrition at a glance with beautiful rings showing progress toward your goals. Review meal breakdowns, track trends, and adjust targets — all without the tedium of traditional calorie counting.

02 / THE CHALLENGE

What needed
to change.

Traditional calorie tracking apps require users to search food databases, select exact items, and measure portions — this adds steps to everyday logging. The aim was to support plain-language meal descriptions and estimated nutrition information.

03 / THE SOLUTION

Thought through.
Built through.

We built a native iOS app with an AI-powered natural language parser that understands food descriptions. Meal descriptions are used to produce estimated calorie and macro breakdowns. Beautiful nutrition rings show daily progress, and meal breakdowns give per-item detail.
