Tenniarb is a macOS application that combines the intuitive visualization of mind maps with the power of a built-in calculation engine. Work with complex data structures and perform calculations without switching between apps.
Professionals are stuck in an endless cycle of switching between tools:
- Create a structure in a mind-mapping app
- Move data to a spreadsheet to perform calculations
- Update the diagram when numbers change
- Try to track where the authoritative version of the information lives
This is inefficient, error-prone, and time-consuming.
Tenniarb lets you:
✨ Visualize complex relationships in a natural hierarchical structure
🧮 Embed calculations directly in nodes — formulas work like in Excel, but within the context of your map
⚡ See results in real time — changing a value automatically recalculates all dependencies
🎯 Keep a single source of truth — all information (structure + calculations) lives in one place
Build forecasts, budgets, and financial models with a clear visual structure of a company or project.
Break initiatives into tasks and automatically calculate effort, risk, and timelines.
Create multi-level system models with built-in calculations for scenario analysis.
Build structured decision models for clients where all calculations remain transparent and easy to modify.
🏗️ Hierarchical modeling
Create tree structures of any depth with unlimited branches.
🧮 Built-in formula language
Formulas operate on nodes like in a spreadsheet. Change a parent value — all children recalculate automatically.
⌨️ Native macOS app
Optimized for Mac with natural integration into the Apple ecosystem. Fast, responsive, and beautiful.
📊 Instant feedback
See computation results in real time as you edit.
🎨 Flexible visualization
Style nodes, group elements, and control how data is presented to suit your needs.
Financial planning
Model company revenue by department → each unit contains formulas to compute its contribution → change a growth assumption and see total revenue update across the map.
Project estimation
Break a project into phases → each phase contains typical costs → add risk buffers with formulas → get a full picture of cost and schedule.
Scenario analysis
Build a decision tree where each branch represents an option → link consequences to calculations → combine scenarios and view aggregated metrics.
Education & research
Visualize mathematical concepts with live formulas that learners can change and see the outcomes.
| Tenniarb | Excel | Mind Map Apps | |
|---|---|---|---|
| Visual hierarchy | ✅ Natural | ✅ Excellent | |
| Built-in calculations | ✅ Yes | ✅ Yes | ❌ No |
| Single interface | ✅ Yes | ✅ Yes (but no calculations) | |
| Intuitiveness | ✅ Yes | ✅ Yes | |
| macOS native | ✅ Yes |
Tenniarb is not a replacement for Excel — it’s a new kind of tool for people who need a structured model with calculations, not just a grid of cells.
- Swift — native macOS experience
- Proprietary calculation engine — fast, reliable parsing and evaluation of formulas
- Modern architecture — optimized for working with large hierarchies of data
Tenniarb is available for macOS. Download the app and create your first computable mind map in minutes.
We believe that working with complex data shouldn't be a struggle. People naturally think in hierarchies and relationships, not in tables. Tenniarb lets you work the way your brain organizes information — while preserving full computational power.
This is a tool for thinkers who compute. For planners who model. For those who don't want to choose between visual clarity and computational power.
