LastPlank

Flooring calculator for Android

See where the last plank lands.

Enter the room's dimensions and your plank's length and width. LastPlank draws every row and every joint, shows how wide the last row will be, and counts the boxes from the planks the layout really uses.

An L-shaped living room drawn in planks, with first and last row widths underneath

See how plank width, room width and the expansion gap affect the last row. Type the room width across the rows, your plank's face width and the gap.

An estimate. Follow your floor's fitting guide.

What it does

The floor, drawn.

Every row, every joint and the expansion gap at the walls, with each row's cut end marked in blue. Pinch to zoom in on a corner.

The last row, before you cut.

The first and last row widths sit under the drawing in large figures. If the last row is thinner than the limit you set, it turns red and says so.

Balance rows in one tap.

LastPlank trims the first row so both sides of the room finish at the same width, and redraws the floor.

Boxes from the real layout.

It counts the planks the drawing uses, adds the spare you choose, and divides by the planks per box or the area printed on the box. Rooms laid with the same plank share their boxes.

Material cost.

Add the price per box, underlay per square metre or foot and trims per metre or foot of wall, and see the estimated cost of the materials.

The cut list.

Row by row, each cut in laying order: "cut to 732 mm", "rip every plank to 101 mm", "from an offcut". Large text and a tick box for each cut.

Offcuts and stagger.

Each row starts with a length that keeps its joints clear of the row before, using a leftover from an earlier row when one fits. You set the gap, the joint spacing, the shortest end piece and the thinnest last row.

Real rooms.

Rectangles, L-shaped rooms, and cut-outs for an island, a hearth or a fitted cupboard. Run the planks across the room or down it.

The job sheet.

A PDF with the shopping list, each room drawn, and its cut list, to share or print.

What it does not do

It does not plan herringbone or chevron patterns, it does not handle curved or angled walls, and it does not plan tile. It does not know product prices: the cost comes from the prices you type. Every figure is an estimate from your measurements, so check the room and each cut before you cut.

Questions

How does LastPlank count the boxes?

It lays the planks on the drawing, counts the ones it uses, adds your spare percentage and divides by the planks per box. If the box gives an area instead, it works out the planks per box from that.

What is a thin last row, and how do I fix it?

When the room width is not a whole number of planks, the last row is whatever is left. If that is a sliver, Balance rows trims the first row so the first and last rows are the same width.

Does it work for laminate, vinyl plank and engineered wood?

Yes. It works with any straight plank laid in rows, from the length and width you type. It does not plan herringbone, chevron or tile.

Can I use inches?

Yes. It follows your phone's region, and you can switch between metric and imperial in Settings. Fractions down to 1/16 inch work.

Does it need an account or cloud storage?

No. Room data stays on your phone, and you can keep a backup file.

Is the cost a quote?

No. It is an estimate of material cost from the prices you type. It does not include labour.

Is it on iPhone?

No. LastPlank is for Android only.

What does the unlock cost?

A one-time $4.99 in the US and £3.99 in the UK, with no subscription. One rectangular room with its drawing, row widths, box count and cost does not need it. The unlock adds multiple rooms, L-shaped rooms and cut-outs, the cut list and the job sheet PDF, and removes the banner. A saved room is never locked.
