Arcwise

Arcwise is a local-first expense analysis app built around spending elasticity. Instead of only listing how much you spent, Arcwise helps you understand which categories react when income, budgets, or monthly conditions change. Record income and expenses, organize spending by category, and review clear visual summaries for income reaction, fixed-cost behavior, flexible categories, and possible compression room. Arcwise highlights high-elasticity categories, low-elasticity categories, and spending areas that may deserve next-month attention. Key features: - Local income and expense records - Category-based spending elasticity estimates - Income reaction trends by category - Elasticity structure charts - High-elasticity category ranking - Monthly budget bounds and formula controls - Watch labels for next-month review - Compression plan text that can be copied for personal use - Starter sample data with one-tap removal Arcwise is designed for simple personal tracking and offline analysis. Your data is stored on your device.
