Field mode

Field mode is for working outside. It turns the whole app to a light, high-contrast palette you can read in direct sun, and makes the keys and type bigger so you can hit them with gloves on. The Settings screen puts it in one line: "Bigger keys, higher contrast — for gloves and sunlight."

Step by step

The quick way, mid-job:

The calculator drawer open. In the bar pinned at the bottom: Field OFF, Settings, History and Help. — Field mode is pinned at the bottom of the drawer.

Open the drawer.
Tap Field mode at the bottom. The sun fills in and the label changes from Field OFF to Field ON. Tap again to turn it off.

The same switch is in Settings ▸ FIELD ▸ Field mode, next to Key haptics. Either one changes the other; the setting is kept until you change it.

What changes

Stairs inputs with Field mode off: the answer bar reading 16 risers · cut 6-3/4" with the green line Headroom, landings and handrails not checked — within IRC 2021 R311.7.1, .3, .5 limits — check local code and Tread 10-1/2" · Rise 9' 0" · Run 13' 1-1/2" · 32.74° under it, then nine input rows visible from INPUT MODE down to STAIR WIDTH. — Field mode off.

The same Stairs inputs with Field mode on: larger type and taller rows, the answer bar wrapping 16 risers · cut 6-3/4" onto two lines with the green check wrapped under it, and the rows running down to NOSING, cut off at the bottom. — Field mode on. Same screen, same numbers.

Light palette. The app switches to its sunlight colours on every screen and every sheet. With Field mode off, the app follows the phone's own light or dark appearance.
Bigger keys and type. Field mode sets a floor under the text size. Keys, labels and the display all grow to it. On the Dimensional Calculator the keys also grow into any height a taller phone has spare. If your phone's text size is already set larger than the floor, yours is kept — Field mode never makes anything smaller.
Less on screen at once. Bigger rows mean more scrolling, and the answer bar under the calculator's name wraps onto more lines. Compare the two shots: the same screen fits two rows fewer.
The numbers do not change. Field mode is only how the app looks.

These help pages follow Field mode too. Turn it on and they go light with the rest of the app.

Field mode is free.

If it doesn't work

The keys did not get bigger. Your phone's text size is already at or above Field mode's floor. You still get the light palette.
The app is stuck in light colours. Field mode is on. Turn it off in the drawer and the app goes back to following the phone's appearance.
