Spanwick: Tape Measure App

Front Porch Apps

About this app

Spanwick is a tape measure for your Android phone that tells you how far off it may be.

Point at two corners and read the length, with its likely error printed beside it. When the phone is not sure, Spanwick says so and asks for a second pass from closer. A phone is not a steel tape, and this app will not pretend it is.

WHAT IT MEASURES
• Length: tap the start, tap the end, or hold and move.
• Height: from the floor at something's foot to its top.
• Floor area and perimeter: tap the corners of the floor in order.
• The room plan: go round the room and the outline draws itself, with every wall's length and its likely error.
• Level: how far a surface is off level, in degrees.
• From a photo: put a sheet of paper or a card in the picture for scale. Works on any phone, even one without AR.

ONE REAL LENGTH CORRECTS THE ROOM
Measure one wall with a real tape measure and type it in. Every reading in that room corrects itself, and you can undo it.

KEEP IT AND SHARE IT
Your room stays on your phone. Square up the corners if you want a tidy plan, then share it as a picture or as a file. Or open a free paint or flooring calculator in your browser with the room's sizes filled in; the app shows you what the link carries before it opens.

BUILT FOR REAL ROOMS
Feet and inches or metric. Lengths you type can be written the way you say them: 7' 10", 94 in or 2 m 40. Dark mode and big text are supported.

NOTHING TO SIGN UP FOR
No ads. No account. The tape, height, area, the level, one saved room and the photo measure are free for life. The camera picture is read on your phone and is never saved or sent. Photos you choose stay in the app until you share them.

WHAT YOUR PHONE NEEDS
The tape uses Google's ARCore. The first screen tells you what your phone can do: Depth, AR or Photo measure. Phones without ARCore still get the photo measure and the level.

Check anything that matters with a real tape before you cut or buy.

What’s new
