About

Rosetta Dash

Read full description

Rosetta Dash is a focused safety and trip-readiness display for road trips, remote travel, and camping. It is not a navigation app and never presents a driver-facing map. See what matters now: • Live heading, GPS speed, altitude, pitch, and roll from your iPhone’s sensors • Tap either attitude instrument to calibrate it to your phone’s mounted position • Current temperature, wind, and visibility • Air quality from Open-Meteo • Active NOAA/National Weather Service alerts when available Rosetta Dash is built for an at-a-glance cockpit view: large instruments, calm hierarchy, and safety conditions above ordinary status. Location is used only while the app is open to calculate local conditions and device instruments. Rosetta Dash has no accounts, advertising, analytics SDKs, or in-app purchases.
