CalcStory: Itemized Calculator

Typed one wrong number in a long calculation? With CalcStory you fix just that number, and the total updates. No retyping, no starting over.

CalcStory is an offline calculator for everyday itemized math: budgets, shopping, renovation costs, expense reports, invoices. Every step stays on screen, every result is saved with the full calculation behind it, and you can come back later to check it or change it.

WHY PEOPLE USE CALCSTORY
• See every step: each amount you enter stays visible, so you never have to remember how you got a total.
• Fix one number: tap any item to edit it, or swipe the live answer to move the cursor to the exact digit. The result updates as you type.
• Edit saved results: bring a saved calculation back, change one amount, and save the corrected total.
• Notes on every calculation: remember what a total was for, like "Groceries, week 3" or "Kitchen tiles".
• Search your history: find an old total by note, by result, or by part of the expression.
• Separate calculation books: keep home, work, and trips in their own books with their own history.

TWO EQUALS KEYS, TWO JOBS
The short equals key adds the current amount to your list and clears the input for the next one. The long equals key totals the whole list and saves it to history, with every step kept.
