I built a Grid Maker as a total beginner — would love feedback...

While researching ideas I found the keyword “grid maker” and tried ~10+ similar products. Almost all of them were apps, so I downloaded a few and read the reviews.

What I kept seeing:
ads everywhere, missing simple filters, grids not staying perfectly square, and you still have to do the math yourself to set the grid.

I can’t really build apps yet, so I made a web version and tried to fix those pain points.
I’m super new to coding. I shipped this with a lot of “vibe coding” + help from Codex/Gemini. I thought this would be a weekend project… it wasn’t. But it’s live now.

Would love to know:

1. What’s the one feature you’d expect from a grid maker?

2. Anything confusing in the flow (upload → grid → export/print)?

   Any feedback is huge — thank you.
