Ruined it

You ruined what could have been great app by caving in to marketing who insisted including an obnoxiously large advertisement of your company name in the middle of the screen. Bigger is not necessarily better. A rookie marketing mistake.

Reasonable precise

I have just checked the measurements against my digital mechanical caliper. The values reasonable matched. It is not a replacement but it is a tool for a specific purpose.

Tape measure

Measurements on phone do not equal the measurements on my tape measure. Enough said
