Looking for a Stopwatch with detailed HR and notifications

Hi guys,

I am looking for a more or less simple app. It is basically a Stopwatch that records HR, sampling every second (or at whatever the shortest interval is possible).

Ideally, the app would:

- Starts with a 2 min prep countdown (configurable)
- Without a user action, switches to a Stopwatch and provides vibration or sound notification at 1 min intervals (configurable 30 sec - 5 min)
- Once interrupted by the user, records the time and sends back to mobile/computer
- Records detailed HR from the Start and provides detailed chart on the watch and on the mobile/computer
- Maintains multi day statistics

If all is too complicated, a simple stopwatch with detailed HR that is displayed after stopped would do for now.

The app is to help to train for dry static apnea for free diving. You can google the process if you like.
