I built a tiny iPad app because I needed to send a marble workshop a precise drawing

Hey,

A few weeks ago I had to replace a custom marble door threshold. The shape wasn’t rectangular, it had an angled cut and a couple of segments that needed to fit perfectly between finished flooring and the door.

The workshop asked for a proper drawing with exact lengths and angles before cutting. I didn’t want to sketch it by hand, scan it and send it, nor opening full CAD for one irregular 2D shape felt like overkill.

I just wanted something simple, like digital graph paper where I could draw the shape, assign exact measurements, and export a clean PDF or DXF.

So I built it. It’s called MilliDraw. It’s a minimal iPad app for precise 2D measured drawings. No subscription, no watermark, just a one-time $0.99 purchase.

I launched it quietly and started talking about measurement workflows on Reddit instead of pushing the app directly. So far it made 13 sales. It’s not huge, but for a tiny niche tool I honestly didn’t expect that.

I’m pretty happy with it!

If you have thoughts, roast it or give feedback.
