Are you investing in dollars or yen? How much will you earn if you sell the foreign currency you exchanged? Is it a loss? It was complicated to calculate, right?

Exchange Profit Diary will help you with your smart currency technology. Go beyond simple exchange rate calculations and systematically record and manage your 'real net profit' that takes into account interest and fees.

📈 Main features:

✍️ Easy record and management Easily record when and how much you exchanged, and what the interest rate was, and manage it at a glance in a list.

📊 Partial exchange support Did you exchange $1,000 and sell it in $300 and $500 each? 'Exchange Profit Diary' accurately calculates the rate of return for each transaction and automatically manages the remaining amount.

💡 Real net profit calculation (considering interest expenses/profits) The most powerful feature of this app! If you record bank deposits or loan interest rates (%) together, it calculates realistic net income that considers opportunity costs and loan interest beyond simple exchange rate gains. You can make smarter investment decisions by understanding at a glance "What if I had deposited this money?" or "How much was the loan interest?"
