Murmur Renovation

Most renovation apps help you draw a room or find a contractor. Murmur is for people doing the work themselves. Enter your measurements and it calculates the materials like a tradesperson would, rounded to the bags, tins and boxes actually sold in stores, with a waste margin included. You get a shopping list to tick off in the aisle, then the installation steps in order, each with a beginner tip and an estimated time. No AI guesswork in the costing. Free, in French.
