I use this app that provides a different challenge every day, where you try to become mindful of something. And the ringtone they have is supercool, is a singing bowl.

As a tech enthusiast I would suggest you some apps to help with this. It will remind you every hour to be conscious in the present. Here you go :

If you make a RC sound, please make one of the selectable totem sounds a light gong. Conscious has a sound like this and it sounds so relaxing. I think it's the perfect totem sound to trigger a RC
Also maybe add a feature to allow you to record your dreams via voice recorder so you can talk it out if you feel like you're gonna forget your dream quickly
