Trueline

About

Who makes this, and what it will and will not say

Who

Sam — Built Trueline. Sam builds software. Trueline came out of a remodeler’s problem rather than a product plan — watching a contractor price a kitchen off a number he could not defend, and deciding the app should say so on the drawing instead of hiding it.

Gilbert Rios — Remodeling contractor, 15 years. Gilbert Rios has been a remodeling contractor for fifteen years. Trueline was built for the way he works, and he is the one testing it on real jobs. He reviews the trade guides on this site.

What this site claims, and how you can check it

ClaimHow it can be checked
Nothing leaves the phone except into your own iCloud.There is no Trueline server. The backup writes to the user’s own CloudKit private database and nothing else opens a socket — the app’s content security policy allows no outside origin at all.
Every measurement is an exact integer, never a floating-point number.Lengths are stored as whole nanometres and money as whole cents, with 820 tests over the arithmetic. A rounding error cannot creep into a quantity because there is no rounding until the moment a number is printed.
Until a tape has been on a wall running each way, every document says so on its face.Each length carries its own provenance — scanned, drawn, measured — and the plan, the takeoff, the proposal and the claim all print it.
Trueline is in testing with a working remodeling contractor.One contractor, in the field, on his own jobs. No figure is attached to this and none is implied.

What it deliberately does not claim

Nobody has yet run a scan against a tape and recorded the difference. Until somebody does, this site says nothing about how close a scan is — which is convenient, because that is also the product’s whole argument.

About the guides

They exist to be useful on their own. No affiliate links, no invented prices for a market nobody here knows, and no paraphrasing of a standard nobody here has in front of them. Where a guide describes the IICRC S500 it says to buy the standard, because that is the honest advice.
