All in one workspace.
WhifCal builds the CSV you already keep into the live structure of the business — what depends on what, where every cost sits, and every value traceable back to its source.
Every value traces back to the file it came from.
Move any assumption and the whole business responds as you watch. Test what you believe, and see how a decision plays out — the cascading effects that used to take months to surface, laid out before you commit to anything.
Every scenario is a copy, so trying a hundred of them costs nothing.
Explore Scenario Playground →This is where the decision-intelligence documents earn their keep. Inside Decision Maps and Scenarios, no number is a mystery — pick any outcome and follow it in both directions.
Something changed and you need to know why. Point to any result — a margin drop, a budget overrun — and WhifCal shows you what caused it and what it went on to affect. The whole chain, in one look.
Every value carries its reasoning with it. Three views, one click each — Path shows where it sits, Impact shows what depends on it, and Calculation Trace shows exactly what's driving the number.
Four document types for everyday planning, calculation, and structured thinking.
A single-column sheet for quick sums, like a budget or a weekly tracker. The simplest place to start.
Explore Worksheets →A nested calculator where smaller numbers roll up into bigger totals. Good for a project budget or a household plan that has to stay organized as it grows.
Explore Plans →A way to map a process from start to finish, like an order moving through a shop or the steps in a hiring round.
Explore Linear Flow →A space to think out loud. Ideas branch and connect on their own, so you can sort out a problem without arranging anything by hand.
Explore Idea Maps →Shared values stay in sync, teammates work on the same live picture, and large documents stay easy to read.
Keep your decision-making smooth & in sync.
Set a shared number once and every document that uses it updates on its own.
Work together in real time, with permission control down to a single node.
Keep large documents readable with label and color filters.
WhifCal also keeps a full history of your changes, supports CSV import and templates, organizes work into folders, and works on both iPhone and the web, in dark or light mode.
WhifCal answers using the data and structure you give it. The values in your documents are real values you brought — not scores or estimates the app invented. It can't tell you about a business you haven't described to it, but once you have, it shows you what you couldn't see before.
Structure what you know, and the answers become visible.
Upload your structured data to create and update documents. Practical for teams running a regular analysis.
For companies that want answers reflecting current data, connect through an API for near real-time access.
Not every decision needs the full canvas. WhifCal Lite is the version made for students, side projects, and early-stage thinkers — all base documents, right on your iPhone.
Find the one that suits your needs the best.
