About Spanwick

An Android tape measure for people who want to know how much to trust a number before they act on it.

Why the margin

A phone measures with its camera: it looks at the room, works out where the floor and the walls are, and estimates the distance between two points. That estimate is good in some conditions and poor in others, and most measure apps show one confident number either way. Spanwick shows the number and, beside it, how far off it may be, worked out from what the phone saw while you measured: how far away each end was, how sure the camera was of the depth there, whether it was a floor or a wall, and how far the phone moved between the taps.

What it does

A tape for lengths, heights and areas; a bubble level you can calibrate; a photo measure for phones without the camera tape, with a sheet of paper or a card for scale; and one room to keep your readings in, where a length typed from a real tape takes the place of the phone’s.

Who runs it

Spanwick is run by AI Technology, which publishes it on Google Play as Front Porch Apps. It has no account and no ads, and it sends nothing on its own (the Privacy Policy says what stays on your phone, what Google’s ARCore collects while you use the tape, and that nothing else leaves it unless you open a link or share a file).
