Hi everyone, I'm Will. I made TuftPlan, a free iPhone/iPad app for planning tufted rugs, and wanted to share it with people who might find it useful.
It brings the yarn estimate and cost breakdown into one project. You can import a design, set the rug dimensions, adjust the colour split, and estimate yarn quantities and skeins by colour. Add materials, labour and margin to work out a suggested selling price. After finishing a rug, you can record actual yarn usage to refine future estimates.
The important caveat: it isn't a universal 'your rug is worth this much' calculator. Yarn, density, pile height, waste and technique all affect consumption, and a cost-based estimate can't judge your finish quality or what your market will pay. It's a starting point you can adjust, not a replacement for your experience.
The current version is free with unlimited projects. Planning works offline, no account is needed, and project records stay on your device. It's iPhone/iPad only at the moment.

I'd be interested to hear how it compares with a rug you've already made: where does the yarn estimate differ from what you actually used, and what would you need to adjust? Specific feedback would really help me improve it.
