Tapely measuring a door: 82 cm wide and 203 cm high with green dots, and a plant pot 24 cm with an amber dot

Most measuring apps guess. Tapely tells you when it's guessing.

Phone AR is good, but not perfect: light, distance and plain surfaces all change how accurate a reading is. Other apps hide that behind a confident number. Tapely shows it.

84 cm ±1 cm

Green: reliable

Good light, close up, a surface with detail. Use it.

46 cm ±3 cm

Amber: approximate

Fine for "will it fit?". For a cut or an order, get closer.

2.1 m ±12 cm

Red: measure again

Too far, too dark or too shiny. Move closer and retake.

Free to measure. Pro when you need more.

Good light

A bright room makes every reading more accurate.

Sweep first

Move the phone gently over the area for a few seconds so Tapely can map it.

Get close

The nearer you are when you tap +, the smaller the error.

Avoid plain and shiny

White walls, glass and mirrors are hard. Aim at an edge or a pattern.

Questions

Is it as accurate as a real tape measure?

No phone app is. In good conditions Tapely is usually within a centimetre or two, and it tells you when it isn't. For anything that must be exact to the millimetre, use a real tape.

Will it work on my phone?

Tapely needs a phone that supports Google Play Services for AR (ARCore). Most Android phones from the last few years do. Google Play only offers the app to phones that support it.

My phone's built-in measure app is going away. Is this a replacement?

Yes. Tapely measures distance for free, and Pro adds height, area and saved photos, without ads or a subscription.

What happens to my camera images?

Nothing leaves your phone. The camera is used only while you measure, and photos you save stay in the app until you share or delete them. See the privacy policy.

Measure honestly.

Free on Google Play. Pro is one payment, yours for good.
