I use pingdom for this, it's very simple and they have a free plan you've just got to look for it on the pricing page which is perfect for the task especially if it's just a free heroku app that you aren't spending money on anyway.
Nice, my googling didn't find anything for this so I decided the irony of using a Heroku App to overcome Heroku pricing was too good to pass up.
