How I built a passport photo app that helps avoid rejection

Hey everyone 👋

I recently wrote about how I built Foxly Passport Photo Maker — a tool that helps people take passport photos at home and avoid rejection.

The biggest challenge wasn’t building the app itself, but making sure photos actually meet strict requirements without confusing users.

I shared the full process here:

Would love any feedback — especially on the product or positioning 🙌
