About this app

Money is confusing. InterestMe helps you make sense of it.

InterestMe is a companion for learning how money works, one small step at a time. Short lessons, tools you can play with using your own numbers, and goals you follow month by month, so the ideas turn into habits.

LEARN, STEP BY STEP
One path of 52 short steps in six parts: see where your money goes, build a safety net, stop paying interest, plan the big moments, make your money grow and plan for later. Most steps let you try the idea with your own numbers. The first steps are free.

FIVE TOOLS
- Budget Planner: split your income into needs, wants and what is left to save
- Savings Goal Planner: how long it takes to reach a target
- Compound Interest Calculator: watch money and interest grow apart over the years
- Loan Calculator: the monthly payment and what borrowing really costs
- Investment Comparison (Pro): what fees take from your savings over time
Every amount is a slider, or tap it to type an exact number. Touch a chart to read any point. Pin your favourite tools to Home.

GOALS YOU KEEP (PRO)
Turn a plan into a goal and follow it on Home. Once a month, a quick check-in logs what you put aside, with a reminder if you want one. In January, a look back at your year.

BUILT TO LEARN FROM
Every input has a plain-language explanation behind the help button. No jargon, no judgment, no wrong answers.
