What's New in G

1.2

August 4, 2026

This update focuses on calibration — making it more accurate and easier in the field: • Finish where you'll work. Calibration now begins by helping you step away from your work area, so it ends right where you'll be measuring — the spot where AR is most accurate. Already 150–200 ft out? Just tap Skip. • Faster Rectangle Layout. The starting corner's elevation is captured the moment you place it, so you only record the other three corners. • A heads-up when you've drifted. If you work well beyond your calibration area — where AR can quietly lose accuracy — the app now reminds you to verify or re-calibrate. • Fewer mis-taps. "Mark Calibration Point 2" stays disabled until you're at least 50 feet out, so an accidental early tap can't cut a calibration short. • True north, made clear. Tap the ⓘ by the compass reading for a reminder that headings are already true north — no magnetic declination to add or subtract. Plus general stability and usability improvements.
