Getting started

Pocketstats is a suite of simulation and analysis tools for small businesses. It includes three tools:

  • Process Map — model a workflow as a network of nodes, run discrete-event simulations, and identify bottlenecks.
  • Spreadsheet Sim — take an existing Excel workbook, mark uncertain inputs as probability distributions, and run a Monte Carlo simulation over your model.
  • Probability Playground — write a quick back-of-the-envelope model in a mini-language and instantly see the output distribution as a histogram.

Quick start​

Process Map​

  1. You sign in and go to App → Process Map. The canvas opens with an empty diagram.
  2. You press S to place a Start node. A Start node appears on the canvas.
  3. You press T to place a Task node. A Task node appears where you click.
  4. You press E to place an End node. An End node appears on the canvas.
  5. You press C to activate the Connect tool, then draw edges between nodes. The nodes connect with an arrow.
  6. You click the simulation icon on any node to set service time distributions. A settings panel opens for that node.
  7. You press Run in the header to launch a simulation. Results appear in the sidebar once the simulation finishes.
Keyboard shortcuts

Use S (Start), T (Task), E (End), and C (Connect) to build your diagram without reaching for the toolbar.

Spreadsheet Sim​

  1. You sign in with a Pro account and go to App → Spreadsheet Sim. The Spreadsheet Sim workspace opens.
  2. You click Upload .xlsx and choose your workbook. Your workbook loads and its sheets appear in the editor.
  3. In the sidebar, you click + Add under Assumptions to mark uncertain cells. The cell is highlighted and you can choose a probability distribution.
  4. You click + Add under Outputs to select result cells. The selected cells appear in the Outputs list.
  5. You set the rep count and click Run. A progress indicator appears and results display when the simulation finishes.

Probability Playground​

Always free

Probability Playground will always be free with an account.

  1. You go to pocketstats.io/app/playground/. The editor opens with a sample model.
  2. You type a model in the editor, for example: revenue ~ norm(50000, 10000); costs ~ norm(30000, 5000); profit = revenue - costs; The histogram updates instantly as you type.

API access​

note

You can authenticate with a session cookie (browser) or an API key Bearer token (scripts and integrations).

All tools expose a REST API under /api/. See the API reference for endpoint details.
