Phone Cycle Timing Engine
The analytical interface is maintained in its own deployment and codebase. This page records the system boundary, source, and launch state.
How it works
Users adjust assumptions about current price, depreciation, and release timing; the app projects buy, hold, and sell windows.
Why it matters
Small consumer decisions also have timing, depreciation, and opportunity-cost dynamics.
What I learned
A simple model can be useful when the assumptions are visible and user-controlled.
Limitations
Prices are estimated from assumptions rather than live resale data.
