Paced Breathing, for Android. Very simple, you can set the inhale, hold, exhale, hold times, and you can set start and end speeds and ramp-down time. You can save settings, so I have a "Quick calm down" that's just 3 minutes, going down to 4.5 breaths/min, and a "Slooow" that 6 minutes long that has me at 3 breaths/min for most of it, and a "Slooow continued" that starts at 3 breaths/min and just continues for another 5 minutes, for when I just want to stay there for a while. I also have a square breathing pattern saved, 6 seconds per side, but I don't much like square breathing. Inhale and exhale is shown visually, by sounds, or by phone vibrations. No other fluff.
