As you suspect, the Heroku cron job launches, executes code, and bills you for its time and the 'worker' process, like the 'web' process, runs at all times.
web: lein run -m myapp.web worker: lein run -m myapp.worker I imagine myapp.worker can just be (while true (println "Working")) for all Heroku cares.
