Useful tools that do not need their own category

General is intentionally small and mixed. It is for tools that help with ordinary questions but do not belong cleanly under money, property, parents, sports, health or developer work.

Use it for timezone planning, measurement conversion and online income scenarios.

Testing online income

Ad Revenue RPM is a scenario tool, so treat the result as a way to compare assumptions about traffic, RPM and conversion rather than a promise.
