ZBee answers one question: how much can you safely spend per year in retirement?

It connects to your brokerage and retirement accounts read-only (or takes manual entry / CSV import) and measures the maximum sustainable annual spend for the plan you actually have - with taxes, RMDs, Social Security timing, and sequence-of-returns risk (Guyton-Klinger style guardrails) in the math. It runs Monte Carlo simulation plus a replay of your plan through every real market sequence since 1928.

Everything computes locally. Your holdings never leave your Mac, and the backend only brokers the read-only account connection. Unlike web-based planners, there is no server copy of your financial data anywhere.

It measures rather than advises: no restructuring recommendations, one transparent assumption set, every assumption disclosed.
