Questions & Answers

As answered by people managing Codewars and WatInside.

Why should a person choose your product over its competitors?

WatInside's answer:

WatInside is built for real home organizing, not business inventory. It’s faster to use because you can scan a label to see contents, add items with photos, and let AI suggest tags for search. It also supports handwriting and NFC, which many alternatives don’t, and it focuses on a clean, modern iOS experience with privacy in mind.

What makes your product unique?

WatInside's answer:

WatInside uniquely combines photo-based inventory, AI-powered tagging, and multiple labeling options (QR codes, handwritten labels, and NFC tags) so you can track what’s inside any box and find items instantly—without opening everything. It’s built to be privacy-first, fast, and simple for everyday home organizing.

How would you describe the primary audience of your product?

WatInside's answer:

People who want to organize and quickly find their belongings at home, especially families, renters/homeowners, and anyone dealing with moving, decluttering, seasonal storage, garages, closets, or long-term stored boxes.

What's the story behind your product?

WatInside's answer:

WatInside was created to solve a simple everyday problem: packing items into boxes and forgetting what’s inside later. The goal is to make storage effortless, label a box, add photos of what you put in it, and later scan the label to instantly see the contents and find anything in seconds.

Which are the primary technologies used for building your product?

WatInside's answer:

SwiftUI, Xcode, GitHub

Who are some of the biggest customers of your product?

WatInside's answer:

• Families organizing closets, kids items, and home storage
• People moving homes or apartments
