# ReceiptCal

Making food logging part of the receipt workflow.

ReceiptCal’s daily dashboard brings calories, macronutrients, and logged meals into one view.

## The problem

Recording meals asks people to repeat a task throughout the day: remember what they ate, find a matching item, and enter a portion. A digital food receipt already contains part of that record. ReceiptCal starts from that existing information and turns supported receipts into a food log.

## My contribution

My work spans the product experience, the application, receipt processing, and the supporting nutrition infrastructure. The product connects a private receipt address with a reviewable daily log. That puts the user workflow and the treatment of incomplete information in the same design problem.

## A smaller input, a useful result

A user can provide their private ReceiptCal address at checkout or forward a chosen receipt. The workflow begins with that receipt rather than access to a personal inbox. It reduces the information the user needs to share and keeps the action tied to a specific purchase.

- 01A chosen receipt

Use a private receipt address or forward a supported receipt.

- 02A daily food log

Bring the receipt’s food information into one reviewable place.

- 03Room to correct

Adjust portions, ignore items, and inspect supporting details.

The receipt-to-log workflow, with review kept in the loop.

## Automation with room for correction

Automatic logging is useful only if the result stays understandable. The log lets a user adjust portions or ignore items, while supporting details explain nutrition sources. Estimates remain estimates. A receipt can describe a purchase without fully describing the portion eaten, so the interface needs room for the user to correct that difference.

## What the product demonstrates

ReceiptCal brings receipt intake and nutrition logging into one product experience. The public product site provides the current app link, supported-receipt information, and an explanation of its nutrition methodology. The daily log is the point where those supporting systems become useful to the person using the app.

## The boundary that matters

The approach depends on the quality and completeness of the receipt and the available food information. Some details can be resolved; others remain uncertain. The central product challenge is to remove repetitive entry while keeping the user able to understand and correct the result.
