Marine Barograph for Android

11 things about Marine Barograph

1. The data are broadcasted from the app via WIFI in UDP mode on a user selected port, so that the app can serve as a position source or pressure source for other navigation programs or devices, which makes it an excellent back-up to standard electronic charting systems.

2. New features in this Marine Barograph app include: automatic storage of atmospheric pressure during all times the app is running, even when in the background, with time and date, GPS position, course over ground (COG) and speed over ground (SOG).

3. Besides the pressure data, your track of GPS positions can also be exported as a GPX file to view in a navigation program or Google Earth.

4. Large digital displays can be viewed from a distance, including prominent pressure trend arrows (visible when data one hour old is available).

5. The stored data are effectively a log of the voyage (or land travel) with navigation information as well as pressure data.

6. On the three-hour display, the official pressure tendency is computed and displayed, and the shape of the curve in view can be used to determine the pressure tendency characteristic code used in official ship reports.

7. The pressure data can be graphed (pressure versus time) over several time intervals from 30 min on up to 16 days.

8. A full Help file with details of operation and tips on the use of atmospheric pressure in navigation is included in the app.

9. The stored data can be viewed from within the app or exported and shared according to time range of the storage files.

10. This app can convert a second or older iPhone (iPhone 6 or newer) not otherwise in use into a valuable stand-alone electronic barograph and voyage data logger.

11. Slide your finger across the graph to read time and pressure at specific points.
