When we decided to buy our first apartment we needed a tool to stop running to the bank to calculate payments and terms. The first version of this app appeared on my and my wife's phones.
When we paid in advance for a car loan and would like to know how much we save every early payment - a second version was developed and we decided to share it with you!
Later, we realized that we need to be reminded. And not just to be reminded, but reminded the way we don't forget.
Have fun! :)
PS. Please note, that calculation is approximate and may differ from a bank.
