Tools, phone apps + SH3D: dimensions, colours and angles
Location: Phone compass / GPS useful if you do not already know.

Angles: there are some phone apps that will act as a plumb / (spirit) level. Handy when measuring angles (staircases, sloping walls).

Colours are more challenging. The best way to find out an existing paint is probably to go to a local dealer with a paint sample. Usually they will have an instrument to analyse the colour and match it. However, it is unlikely it will be 100% accurate.

Actual paint used on the house: 225,225,221 (#e1e1dd)
Local shop sample analysis: 212,212,207 (#d4d4cf) - slightly darker, but similar balance
Phone app reading: 219,214,216 (#dbd6d8)

The phone app reading varied, but exaggerated the red (shade on a bright day). I had better results (balance, if not lightness) with indoor tiles. So apps/camera colour balance cannot be counted on for full accuracy and must be checked. Still, I keep using this app for measuring colours. It is closer than my guesswork.

For SH3D rendering, there is of course shades, colour temperature of lightsource etc etc.

All in all, I keep using these apps (along with a laser measure) when drawing, and find them surprisingly useful and timesaving when drafting with SH3D. No view on specific apps, there are several.
