This app is designed for people who have trouble waking up or creating an exercise routine.

UpBeat Heart rate Alarm requires you to either get your heart rate up to a level you set to turn off the alarm or pay a laziness fee to turn it off.

This app uses HealthKit to monitor your heart rate via Apple Watch or iPhone Camera Optical Lens with your finger tip. Consult your physician before using this app. If you have a heart condition or any medical condition where exercise is not advisable do not use this app.

If app doesn't show up on Apple Watch go to iPhone Watch app .
My Watch > UpBeat > Toggle On 'Show App on Apple Watch'

*Note: First time your Apple Watch gets your heart rate via app may take over a minute. After that it is pretty immediate.
