What's New in FieldLab Mobile
2.0.0
July 21, 2026
FieldLab Mobile 2.0 is a complete redesign of the app, rebuilt from the ground up for 2026. Your existing data comes with you — all of your data sets from previous versions are automatically converted to Test Runs when you update. WHAT'S NEW IN 2.0 • Log multiple gauges in a single Test Run — record pressure and temperature from every sensor simultaneously, each reading timestamped so your complete test data lives in one place • View all readings on one time-based graph to spot correlations and pinpoint exactly when changes occurred • Export traceable reports as PDF, CSV, or graph image — every export includes the manufacturer, model, and serial number of each gauge used • Name your gauges and readings — label by location, function, or asset number so every data point is clearly identified in graphs and reports • Works with all Bluetooth-capable Ralston gauges, including older models
