Hey r/CNC,

I'm a solo dev. I made an iOS app called DXF Viewer – CAD Measure Tool for opening and measuring DXF files on iPhone/iPad — handy when you're on a shop floor and don't want to fire up the laptop.

App Store link: https://apps.apple.com/id/app/dxf-viewer-cad-measure-tool/id6762408082

A user just left a one-star review that says, in full: "Total rubbish, does not work."

That's all the detail I have. No DXF attached, no description of what they tried, no email. And I genuinely can't tell if:

their specific DXF file failed to parse
they expected editing and got a viewer
the trial/paywall flow felt like the app was "broken" rather than gated
something on their device (iPad? older iPhone?) is rendering nothing
it's a competitor / random spite review

If anyone here uses DXF on mobile, I'd really value blunt feedback:

Does the app actually open your DXFs? If not, what version/source (AutoCAD R14? 2018? Fusion export? LibreCAD?).
Is anything about the UI/flow misleading — does it look like it should do something it doesn't?
Is the trial gating annoying enough to feel like the app "doesn't work"?

Happy to send a promo code to anyone willing to poke at it and tell me what sucks. Roast freely — I'd rather hear it here than read it on the App Store.

Thanks 🙏

I built a DXF viewer for iOS and got one-star reviews saying "Total rubbish, does not work." Can someone help me figure out what's broken?
