About this app

Japan Post Bank also charges a coin deposit fee, and if there is a lot of 1 yen, it may be in the red. On the other hand, the supermarket "Coinstar" has a service that can be exchanged for banknotes by paying a fee, but the fee is 9.9% of the amount, so if there are many high-value coins, it will be more expensive than Japan Post Bank. This smartphone app can calculate and compare two types of fees.
This app is a sample app of the book "Engineers developing mobile apps should develop with Prism and Xamarin.Forms".
