Cold Plunge

Activity to track time spent in cold water (cold plunge). Default time is 3 minutes with ability to extend timer. Garmin team - please help, this is my first attempt at an app and I encountered issues trying to correct the launcher icon from 24x24 to 40x40. Please help me correct this so I can successfully run the test. I'm really excited to create this for other users and myself - there's no monetary fee, I just wanted to create a better way to track cold plunge activity. My email is [email protected] and I'm open to suggestions or help fixing this. Thank you
