With your server started, you may now go to your Neo4j browser and input the following query:
CALL dbms.functions() YIELD nameWHERE name STARTS WITH 'apoc.'RETURN count(name)UNION CALL dbms.procedures() YIELD nameWHERE name STARTS WITH 'apoc.'RETURN count(name)
This is a UNION query that will return two lines, fortunately with non-zero numbers. My result at the time of writing this is 98, then 201. Note that this is not using APOC, but built-in functions.
This means 98 functions and 201 procedures. I presume that soon, the formidable community and the uncomparable Michael Hunger (@mesirii) will reach 365 functions ...
