Building Arveno

We could print fake decimals. We label the error instead.

Nothing stops an app from displaying 18.34%. Nothing except honesty about how the number was made.

The short version

  • Every method carries error
  • False precision is a design choice
  • So we made the opposite choice
  • Honest numbers compound

Every method carries error

Lab scans, electrical scales, callipers, photos — all of them estimate. The difference between tools is whether they say so.

False precision is a design choice

Two decimal places on an estimate isn't accuracy — it's costume. It borrows the look of science to dodge the questions science would ask.

So we made the opposite choice

Arveno calls its numbers estimates, in the interface, on purpose. A directional read you can trend — never a lab verdict in fancy dress.

Honest numbers compound

An estimate taken the same way every time becomes a trend you can act on. A fake-precise number becomes a disappointment with decimals.

Measure it instead of guessing

Arveno turns one photo into honest body-composition estimates — labelled as estimates, tracked as a trend. The first scan is free; membership is £1.99/month or £19.99/year, with the first 7 days free either way.
