Story Calculator: Steps Stay

A calculator that keeps your working, so you never wonder "what did I just calculate?"

Normal calculators erase the process once you get an answer. This app keeps each expression and subtotal as a line-by-line "story" you can review, edit a single number in, and recompute from there.

■ Who it's for
- Multi-step calculations where you need to find the mistake
- Discounts, tax-in/out, bill-splitting you redo often
- Showing or sharing how you reached a number

■ Key features
- Calculation story: expressions and subtotals kept as lines
- Edit a line's value and everything after recomputes
- Finance presets: discount, tax in/out, split, tip
- Share/copy the history as text
- Fully offline / no account

■ Design philosophy
A calculator's weakness is that the process vanishes. Keep the steps, and it becomes a tool you can check, correct, and explain.

Not just the answer — how you got there stays.
