家計簿

I've simplified the overcrowded parts of my app as much as possible,
while still retaining features like percentage of income, year-over-year comparisons, annual totals, and past four-year comparisons.
A list of standard items is created, so all you have to do is select from them.
For income and expenses, simply enter the amount.
The text only accepts integers.

How to access the data after creating a CSV file for reference

Smartphone
Connect to your computer with a C-terminal/USB cable.
Enable USB for file transfer.

PC
→ Click "Relevant Smartphone" → Click "Internal Storage"
→ Click the "Android" folder → Click the "data" folder
Click the "jp.gr.java_conf.lotorich.lkakei" folder
→ Click the "files" folder → Click the "Download" folder
Finally, you can access the saved data.
The data name is Lkakei
(Although it's CSV data, it should display in a Microsoft Excel spreadsheet.)
