About Remindum

A useful place
to work things out.

Remindum is a small collection of tools for everyday calculations and decisions.

Clarity before complexity

Sometimes you need a number: the interest on a starting amount, a monthly loan payment, or the days between two dates. These tools keep that task in focus, then explain the method so you can judge the answer.

Estimates with their assumptions attached

Financial tools use rates you enter. They do not quote current bank offers or promise returns. Each tool includes a worked example and its limitations. Calculations run in your browser; this version has no analytics or advertising scripts. Your hosting provider may still receive ordinary request information.

How this project is being built

AI assists with code and explanation drafts. Mathematical unit tests check the calculation models. Those checks do not establish professional financial advice, external product testing, or expert authorship. This initial version is under development and has not completed a production launch audit.
