I built Plan² because I wanted a better way to lay out a business space before spending money on it. If I move the counter, is there still enough room in the aisle? Will that display case actually fit? With Plan², you can try those ideas on a floor plan and walk through them visually in 3D before you buy fixtures or start building.
I come from running retail stores, and this is the first app I’ve tried to build without a company helping me. I made it to solve a problem I’ve dealt with myself, and I could use your help making it better.
If something feels confusing, takes too many steps, or just doesn’t work the way you expected, tell me what you were trying to do and where you got stuck. And if there’s a feature you wish you had while planning your space, I’d love to hear about it.
Thanks for giving Plan² a try.
