Online digital training, instruction, guidance and documentation We help you digitise your processes and document them. Minimise your risks by regularly automatically instructing all employees in all areas of occupational safety and other compliance issues.

We protect you from that. Our learning and documentation platform HSE 4.0 records all training measures. We document all required compliance training, whether presence format, blended learning or online audit-proof as well as the legally required surveys. Instruct and learn: We provide you with the following templates for the following topics: occupational safety, compliance, GDPR, hazardous substances, environmental management, waste disposal, and many other templates for general topics.

About

ArboRefD

Read 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 call

The clearest difference is in-app purchases: HSE 4.0 at none against ArboRefD's 8. HSE 4.0 also leads on iOS requirement (13.0 vs 15.6). ArboRefD's advantage is update cadence (every 4 weeks vs every 8 months) and device support (4 vs 2). On price and ads there is nothing between them.
