Most budgeting apps require you to link your bank or spend hours on manual setup. Fin (USEFINAPP) works differently. Upload your bank's CSV and AI can categorize everything instantly for you. Then ask the assistant real questions about your spending and actually get answers. No methodology to learn, no bank credentials to hand over, no complexity to fight through. Just instant clarity on where your money is going. Built by an indie dev who genuinely loves feedback. $5.50/month.
