The CheckTrees app assists professional arborists performing tree assessments including mapping, treatment recommendations and associate organisms overview. The data can be uploaded to the CheckTrees.com website where it is possible to browse them on a map and upload photos of the trees. The uploaded inventory can be released using credit units which can be obtained via in-app Google Play purchase, credit card purchase or via invoice. The released inventory can be exported to Shapefile or XLS for further processing or delivery to the client. The inventory can be also published on the CheckTrees.com website and assigned to the client. A free CheckTrees.com arborist account is necessary to log in to the app.
