Offline everyday calculator collection
An app that brings everyday calculations together offline. I placed differing inputs and rules within a shared structure and implemented result sharing as text, images and CSV files.

Managing different calculation rules
Tax, salary, property, finance, health and general calculations are organized by feature. I separated calculation logic, presentation and storage, with a use case for each calculator.
Sharing results and updating rules
Results can be exported as text, PNG cards or CSV files. Calculations affected by tax or rate changes are treated as needing updates to their domain rules as well as their app code.
