Meet Zlpy. Zlpy will help you stop music/podcasts when you fall asleep. Zlpy measures your hear beat and from a level you define it will then paus music/podcasts when this level is reached. Zlpy also have a nifty sensitivity setting that allows you talk small dips in hear rate. This can be useful for mindfulness exercise where you don't want to miss out if you fall a sleep. Your session is stores to Health Kit where you see your hear rate during the process.
