Business Idea Evaluation: shopping list app with optimal route planning

When doing in-person shopping at walmart, I often find myself unable to locate items and walking repeated distances because of bad route planning. The walmart app is useful, but if my shopping list is long, searching each product in the app gets inconvenient.

What I've created is an app where you only need to input your product search queries, and the app:

automatically populates product information such as prices, picture, aisle, and title

reorders your shopping list in a way that minimizes walking and saves time.

Obviously ordering pickup or delivery also saves time, but compared to in-person shopping, I'd say both have pros and cons. My app basically enhances the in-person shopping experience but doesn't save as much time as ordering delivery because at the end of the day, you're still walking around in the store.

To publish the app, I'd need to add a lot more things such as a landing page, error handling, server configurations, etc etc etc, which all goes beyond the scope of my personal use. So before I do all that, I'm trying to talk to potential users. I appreciate your feedback!
