What's New in FieldLab Mobile
2.0.1
August 19, 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. • 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 WHAT'S NEW IN 2.0.1 • Chart view now can handle multiple different pressure or temp units, each with its own axis • More reliable Bluetooth connections — gauges that go out of range now reconnect automatically and rejoin the test in progress • No more false "gauge stopped early" alerts when a gauge is temporarily out of range during a test • Test Run data is safer — if a gauge is out of range when a test ends, the app keeps retrying until your data is safely transferred, even if the app is closed in between • Resuming test sessions 100% more reliable • Large data sets now open instantly and scroll smoothly • Improved PDF and CSV reports — reading types are labeled and every value shows its units • Many more bug fixes and performance improvements
