Build your nutrition tracker.

How to build your nutrition tracker

1. 1

   Describe the job

   Build a food log that keeps quantities, source labels and corrections visible.

2. 2

   Review the first version

   Choose how the log owner records the food entry and how the nutrition-data reviewer reviews the next step.

3. 3

   Refine the views

   Ask First to adjust the fields and views for the people who will use the app.

4. 4

   Test before sharing

   Walk through the process with a sample record and check who owns the next action.

What to include in your nutrition tracker

• Keep the food entry in context

  Keep food entry, quantity, source label, nutrient assumption, correction and history together so the next person can understand the request or record.

• When the next step needs a decision

  A logged serving uses a different quantity from its source label. Expose the assumption and let the user correct the entry.

• Keep history visible

  Keep an uncertain nutrition estimate labelled rather than presenting it as a measured value.

• Choose what each person needs

  Give the log owner a working view and the nutrition-data reviewer a review view. Keep food entry and quantity attached to the decision as the work moves between them.
