Emlid Flow, formerly known as ReachView 3, is an Android app developed by Emlid Tech Kft. that serves as a companion app for Emlid Reach receivers. This app allows you to configure your devices, perform survey activities, and manage your work data all from one place.

With a built-in coordinate system registry consisting of over 1000 systems and the ability to create custom coordinate systems, Emlid Flow offers great flexibility. Other base features include collector and stakeout tools, base shift, and file import/export in CSV, DXF, or Shapefile format.

The app also offers more advanced features for users with a free Emlid account.
