Check your portfolio's structure, not what to buy. Give it your holdings and it maps your allocation, flags concentration risk (single stock, sector, region), and calculates rebalancing math toward a target you set — all as diagnostics, never security recommendations. Runs on real, live-retrieved prices, never estimated ones. Not financial advice; built for a repeatable weekly or monthly self-review, downloaded once and run whenever you want.
