Just a pretty UI, not a good App for Expense tracking
You can not set the currency for Japanese Yen (or any other). Anyway I set 300,000 as my budget (as it would be in Yen) and found it can not handle big numbers. Slowly counting down on Overview and I need to wait and wait just to check the balance.
I recommend look at other Apps which has other useful features as password protection, integration with desktop, budget planning etc. I regret buying this App.
