Bird Count
Read full descriptionHide full description
This App facilitates the geotagging of Bird Count stops and the return to the same stops during the next and subsequent Bird Count sessions. Stops in an open meadow or forest aren't always easy to reproduce. Using GPS it is possible to return to within a few (3-10) feet of each stop. The apps use is not restricted to Bird Counts but that is the primary reason for its development.

Verdict
The clearest difference is update cadence: B4i at every 3 months against Bird Count's every 15 months. B4i also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.6). On price, ads and in-app purchases there is nothing between them.
