FX収支管理 is a free Android application developed by otak-lab. It is a finance app that enables users to manage their forex transactions in a single platform. The app allows users to enter transaction details such as trading date, transaction type, currency pair, lot size, swap, profit/loss, and trade memos. Additionally, users can attach images such as charts or account screenshots to their transactions.

The app's graph screen displays the profit/loss (bars) and balance (line) of the entered transactions on a graph. Users can swipe from right to left to view the performance of each currency pair in a pie chart. The graph can be changed to a monthly or yearly view. Tapping on a monthly bar graph displays the transaction details for that day, while tapping on a yearly bar graph changes the graph to show the performance for that month.
