Works, but too much marketing. – Runtastic Heart Rate PRO Review

Update: it remains rude to paid customers, as described below. Weak. --- This app does indeed measure pulse rate reasonably well. But paid customers who choose not to create an account have to click through not one but two layers of marketing gubbish to start the app and take a pulse. EACH TIME.
