Context
Stockt was built as a two-person university project exploring how mobile tools could help households manage food inventory and reduce waste. Starting from an initial prototype structure, we redesigned and refined the experience through usability testing and iterative improvements.
Scope
The prototype includes inventory creation, item management with photo support, expiry visibility through simple indicators, filtering for expiring items, and a barcode scanner that evaluates products against user dietary preferences. Scanned items can optionally be added to the inventory, while expiry dates remain manually selected using the Android date picker.
My Contribution
I redesigned and refined the app's interface starting from an initial base implementation. I created the hi-fi prototype and updated user flows in Figma, then implemented the revised screens and interactions in Kotlin. Together with my teammate, I designed the usability study and conducted interviews. Based on the test results, we iteratively adjusted navigation, visual indicators, and interaction details to reduce confusion and improve clarity.
Research and Iteration
We evaluated the prototype through heuristic evaluation, SEQ and SUS questionnaires, and A/B comparisons of expiry visibility and filtering. The findings highlighted issues around navigation and indicator clarity, which led to refinements in labeling, iconography, and entry points for key features such as scanning and filtering.
