The Calling Tree puts emergency communications and business continuity information directly into the hands of your people. Send urgent communications to individuals, teams or your entire organisation using Push, SMS and Voice, with responses tracked so you can quickly see who has received and responded to a message. Messages can be prepared in advance through the secure web administration system or created directly within the app when an incident occurs. Flexible access levels allow authorised users across the organisation to communicate with the people and teams they are responsible for. Staff can check in during an incident, giving managers an immediate view of who is safe, who is available and who may need assistance. Each user has access to their own calling tree or call cascade, clearly showing who they are responsible for contacting and who is responsible for contacting them. Business continuity plans, emergency procedures, documents, maps and disaster recovery information can be distributed directly to users and centrally maintained by administrators. Crucially, key information is stored securely on the device, so essential plans and contact information remain available even when network connectivity is disrupted. Organisations can also allow users to maintain their own emergency contact details and communication preferences, with optional consent controls where required. The Calling Tree helps organisations communicate faster, account for their people and keep critical information available when normal operations are disrupted.
Decision tree
Visually build and manage complex decision trees to analyze choices and their potential outcomes. Automatically recalculates values and identifies the optimal strategy based on costs, probabilities, and net values. Supports intricate trees of any depth for comprehensive analysis.
- Intuitive visual decision tree construction
- Define alternatives with costs
- Specify outcomes with payoffs and probabilities
- Dynamic arrangement of tree elements
- Automatic value recalculation
- Identification of optimal strategy

The Decision tree app offers a powerful visual interface that allows you to intuitively build and manage complex decision trees. You can easily annotate new alternatives and outcomes, adjust their levels within the hierarchy, and even drag entire branches to different positions within the tree. The app automatically recalculates all necessary values to reflect any changes, ensuring that your analysis stays accurate and up-to-date. Each alternative in the tree has a cost, which represents the expected expense of pursuing that option—like $220,000 for opening a new branch in another city. These alternatives are represented as blue-collar elements within the tree and can lead to multiple outcomes. For instance, the outcome of opening a new branch might include a potential increase in turnover, but also the risk of reduced quality due to management challenges. Each outcome has an associated value, which can be positive or negative, and a probability indicating the likelihood of that outcome occurring. The probable value of each outcome is calculated by multiplying its value by its probability. The net value of an outcome is determined by the weighted influence of the outcome’s value on the overall expected value of the corresponding alternative, minus the cost of implementing that alternative. The Decision tree app supports decision trees of any depth, where after an outcome, you may encounter another decision alternative, which in turn may have its own outcomes, and so on. This capability allows you to create and explore highly intricate decision trees. The optimal strategy is identified by tracing the path from the root alternative through the branches that lead to the highest net value. This path represents the best course of action based on a comprehensive analysis of all possible alternatives and outcomes—a task that would be virtually impossible to perform mentally or with a simple paper and pencil due to the extensive calculations required. With the app’s dynamic interface, you can quickly adapt to changing scenarios, and the app will handle all the complex calculations automatically. The complexity of decisions involving significant uncertainty brings challenges such as unpredictable consequences, multi-layered factors, potential reduction of uncertainty through additional information and the influence of the decision maker's attitude to risk. To manage this complexity, users often look for best practices. Leverage the effectiveness of decision making by applying a decision tree, a proven analytical approach that provides clarity and leads to informed decisions in the midst of uncertainty. Features: -Intuitively construct a visual decision tree for a comprehensive decision analysis. -Generate alternative elements with detailed descriptions and associated costs. -Define outcomes for each alternative and specify payoff amounts and probabilities for thorough evaluation. -Dynamically arrange elements to create parent-child relationships at any depth in the tree. -Construct sequential decision chains that allow subsequent decisions based on specific outcomes. -Enter the cost of each alternative to accurately assess the impact of the decision. -Specify nominal profit values and probabilities for each outcome to refine the decision criteria. -Automatically calculate the path value resulting from the multiplication of value and probability. -Calculate the net profit, i.e. the result obtained by subtracting the cost of the alternative from the path value of the outcome. -Automatically visualize the best strategy based on the criteria for the optimal expected value.

Verdict
The clearest difference is review sentiment: CallingTree at 100% against Decision tree's 0%. CallingTree also leads on in-app purchases (none vs 2) and iOS requirement (15.6 vs 17.0). Decision tree's advantage is update cadence (fortnightly vs every 7 months). On price, ads, monetization model and device support there is nothing between them.
