ArboRefD
Read full descriptionHide full description
ArboRefD helps evaluating the breakage safety of trees with localized defects whose trunk still has an intact cross-section higher up. This is one of the practical applications of Allometric Self-Referencing (ASR) for evaluating the breakage and uprooting safety of defective mature trees. To document the results for a specific tree, we recommend saving a screenshot after entering all data in the current version. Additional features are currently being developed for the app. If you buy the app with a one-time purchase and enclose the corresponding app invoice with your next order of a measuring device (ABT, DNT, RES) from RINNTECH, you will receive a discount.

Verdict
The clearest difference is in-app purchases: Tree Risk Assessment at none against ArboRefD's 8. ArboRefD's advantage is update cadence (every 4 weeks vs every 4 months) and device support (4 vs 2). On price, ads and iOS requirement there is nothing between them.
