Tile takeoffs are where bathroom and kitchen quoters lose half an hour. You count tiles by eye, add the manufacturer's 10% waste, hope you didn't miss the awkward border row by the bath, and the supplier still rings to say you're three boxes short on delivery day.
Snap one wall photo with a 2p in shot for scale. Hint reads the tile size, counts the grid, adds the right waste % for the pattern (offset, herringbone, straight) and tells you how many boxes to order — so the supplier stops ringing on delivery day.
Free to start. Open it and have a go — pay only when it's pulling its weight.
