My wife is an architect (the building kind, not the software kind). Whenever we need to plan anything for our home, she pulls up Revit. It's been amazing for things like our kitchen renovation, but it's a lot for simpler things like experimenting with furniture layouts or making sure the side table we spotted at IKEA would actually fit. I tried a few apps and websites. Everything was either too expensive or more than I was really looking for. So I built SnapDraft: something quick, simple, and easy enough for a non-architect like me to use and pull up from anywhere.
Hope it's useful for you too and if you have any feedback, share it my way!
