Unit by unit.
Each apartment has its own point in county 911 records. Spot pins the one on your order.

Spot is a map for delivery drivers. Enter the address and unit, and Spot pins the building that unit is in, from the address records counties keep for 911.
Big complexes hide their units behind one street address. Spot uses the county's own records to find the right one.

See the complex's name on the pin, and the right building even when the order uses the leasing office's address.

Directions end at the building, with your county saved on your phone for spots with no signal.

Better directions, not a promise. Address records can be out of date, and they don't always agree with the map. Spot gets you closer; the signs at the building still have the final word.
