The challenge

Tracking nutrition shouldn't feel like a second job

The biggest barrier to consistent calorie tracking is friction. Searching for every meal in a database, logging individual ingredients, and manually calculating macros takes time users don't want to spend. Most people quit within a week.

The client wanted an app that could do the heavy lifting — scan the barcode on any food package and populate all nutritional data automatically, calculate a personalised daily norm, and give users a clear picture of their progress without overwhelming them with numbers.

Our approach

Make the right action the easiest action

We designed Noura around the concept of "one tap logging." Every screen is built to minimise the steps between intention and action. Scanning a food label takes under three seconds. Adding a meal from history takes one tap. The dashboard shows exactly what matters — calories remaining, macros balance, water intake — without visual clutter.

We chose React Native for true cross-platform parity and Firebase for real-time data sync across devices. The OCR pipeline runs on-device for speed, with a cloud fallback for unrecognised labels.
