JointLine Tile Layout

JointLine is a focused tile-layout planner for installers, remodelers, and detail-minded owners who want the visible field resolved before adhesive opens. Enter room, tile, and joint dimensions to visualize a centered grid with perimeter cuts and focal axes. JointLine balances opposite edges and deliberately removes a full course when the centered cut would fall below one quarter of the tile dimension. Cuts view turns the result into readable millimeter values. Order view applies waste allowance and box coverage to the room area. JointLine is an estimating and layout aid. Verify actual site dimensions, squareness, movement joints, pattern repeat, manufacturer coverage, lot matching, codes, substrate requirements, and professional guidance before ordering or installation. Layouts stay on the device. There is no account, cloud sync, analytics, advertising, tracking, subscription, in-app purchase, AI processing, or backend upload. JointLine is a one-time purchase.
