Surveying In the Field, developed by TopOntheFly, is a free Android app that offers a simple yet efficient solution for surveying tasks. This app can be used independently in the field with any total station. It comes with two modes: StakeOut and Survey.

In StakeOut mode, you can use either the keyboard or data from a file to perform the task. Meanwhile, in Survey mode, you can store measurements and coordinates in a file. The app is straightforward and easy to use for those who are already familiar with surveying tasks.

Additionally, the app developer recommends downloading their other free apps, "Geodetic NET" and "Topography On the Fly," from Google Play. The app is open to feedback and ratings from users.
