iPhone
A quick timer and a noise meter are here. Turn your records into a one page report with a site photo, and watch one ad to stay banner free all day.
Field Master is a tool app for calculating, measuring and keeping a record right there on site.
Scientific Calculator
Trigonometric and inverse trigonometric functions, logarithms, square root, square, reciprocal, factorial, percentage and sign change. Copy a result or save it straight to the log, and recall earlier results from the history.
AR Distance and Volume
Measure between two points with the camera. Before you place a point, a guide line and its length are shown, so you retake fewer measurements. Place four points and you get the volume too. Devices with LiDAR lock on more precisely, and you can switch between m, cm and ft.
Bubble Level
Lay the phone down for horizontal, stand it up and it switches to vertical by itself. It reads correctly even face down, and a light vibration tells you when it is level.
Quick Timer
Start timing just by laying the phone down or standing it up, so it works with gloves on. Count down or count up, and it sounds when the time is done.
Noise Meter
Read how loud it is right here in dB and keep it in the log. Four bands tell you at a glance how quiet or loud the place is.
Log and Reports
Values from the calculator, distance, volume, level and noise meter are saved with your notes. They group by date, you can search and filter by type, and export to CSV. Add a site name and a photo and build a one page report to send to a client or the office.
About ads
No feature is placed behind an ad. Nothing interrupts you while you measure a distance or check a level. Tap the chip at the top right of the home screen, watch one ad, and the banner stays away for the rest of the day.
Seven Languages
Korean, English, Japanese, Simplified and Traditional Chinese, Spanish and French, switchable inside the app at any time.
Records stay on your device and are never sent to an outside server. No sign up is needed.
AR distance measurement and the level are quick reference tools for the field. For work that needs precise figures, please also check with a real measurement such as a tape measure.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixed a problem where level and calculator entries disappeared if you closed the app right after tapping Save. Entries are now saved the moment you tap, and you'll see that they're saved. Deleting an entry or editing a note is kept right away, and CSV exports include your edited notes.
The calculator now handles a negative after a power, like 10^-3, and shows a result even if you forget a closing bracket.
The noise average is now calculated from sound energy, and the quick timer no longer plays its sound twice or late. If camera access is off, AR Measure shows you how to turn it on.
