WILL IT WORK ON MY ANDROID PHONE?
This is an excellent question. Due to the nature of the Android
system, we are unable to guarantee that it will work
on any particular Android phone until we have had the
opportunity to test the app on that model.
The current version works reliably
on Android version 4.0 (Ice Cream Sandwich) or later,
on the following devices:
Samsung Galaxy S5
Nexus 7 tablet

Samsung Galaxy Note 10.1
Tips for using Observer Pro:
Mapping points, lines and polygons

- The blue dot shows your current location.
- The pale blue circle shows accuracy.
- The red dot shows your observation location.
To add a point, choose Point from the Draw: menu.
A red dot will appear on the map at your current location.
- Drawing on the map uses two gestures:
- long press (more than half a second)
- short press (tap)
- To delete a red dot,
short press right on top of it.
A dialog will ask you to confirm.
- To move a red dot,
long press right on top of it.
When your finger acquires the dot, the dot jumps up
to make it easier to see.
Drag the dot where you want it.
- To draw a polygon: choose Polygon from the Draw: menu.
To draw a polygon free style,
long press where you want each vertex.
When you add a new vertex, a line appears connecting it to the previous vertex.
As soon as there are three vertices, the polygon area
appears in light red.
The sides of the polygon are shown as dark red lines.
The order of vertices is important! When you add a new vertex,
it goes in between the last vertex and the first vertex.
To draw a polygon around the preimeter of a patch of plants,
walk around the patch, and press Append Point every few seconds,
or whenever you change direction.
