Excellent when it worked
For about a week now, the app is "stuck" on date 09/06/2015 @ 19:00 hrs and displays 33 ppm (which leads me to suspect that PLA hacked this app)
Doesn't work anymore
It was useful when it actually worked..
Intermittent
Works intermittently. When working, it does what it's supposed to with no extra gimmicks. This is nice but the only problem is its reliability. Mine hasn't updated for two weeks...
