パチ収支Free is a free Android app that helps you keep track of all your income and expenses related to pachinko and slot machines. As soon as you launch the app, you will see a calendar screen where you can select a date to enter your income and expenses. You can also long-press on a date to quickly access the input screen. The app offers other features such as a machine list, store list, list display screen, and analysis screen. The machine list and store list can be sorted by order of registration, most recently used, and other conditions. The list display screen allows you to filter your income and expenses data by year, month, store, machine, and memo. The analysis screen displays your income and expenses data in a bar graph, which can be filtered by year and month and compared between stores and machines. You can also back up your data to your SD card or internal storage. However, the free version only allows you to save data, not read it. If you want to read your saved data, you will need to upgrade to the paid version.
